Abstract

A recording medium, including: an ink-receiving layer configured to receive an ink for inkjet recording; and a transparent sheet having a total luminous transmittance of 50% or more, wherein the recoding medium has a layered structure in which the transparent sheet and the ink-receiving layer are sequentially stacked, and the ink-receiving layer includes a gap-absorption-type ink-receiving layer including a composition including at least inorganic fine particles and polyvinyl alcohol having a weight-average polymerization degree of 2,000 or more and 5,000 or less and a saponification degree of 70 mol % or more and 90 mol % or less.

Claims (49)

1. A transferring material, comprising:

an ink-receiving layer configured to receive an ink for inkjet recording;

a transparent sheet having a total luminous transmittance of 50% or more;

a releasing layer comprising a composition including a release agent; and

a base material sheet serving as a support for the releasing layer,

wherein the transferring material has a layered structure in which (i) the ink-receiving layer, the transparent sheet, the releasing layer, and the base material sheet are sequentially stacked, and (ii) the transparent sheet and the ink-receiving layer are in abutment with each other,

wherein the ink-receiving layer comprises a gap-absorption-type ink-receiving layer comprising a composition including alumina fine particles having an average particle diameter of 120 nm or more and 200 nm or less and polyvinyl alcohol having a weight-average polymerization degree of 2,000 or more and 5,000 or less and a saponification degree of 70 mol % or more and 90 mol % or less,

wherein a content of the polyvinyl alcohol in the ink-receiving layer is 3.3 parts by mass or more and 100 parts by mass or less with respect to 100 parts by mass of the alumina fine particles, and

wherein an image is recorded with a pigment ink comprising a resin dispersion-type pigment, and the transferring material is used for transferring the image onto a transfer member.

2. A transferring material according to claim 1 , wherein the transparent sheet and the releasing layer are in abutment with each other, and

the transferring material has the layered structure in which the releasing layer and the base material sheet are in abutment with each other.

3. A recorded matter comprising:

an image support on which an image is supported; and

a transferring material as recited in claim 1 on which the image is recorded,

wherein the recorded matter has a layered structure in which the image support, the ink-receiving layer, the transparent sheet, the releasing layer, and the base material sheet are sequentially stacked.

4. A recorded matter according to claim 3 , wherein the base material sheet and the releasing layer are released, and a surface of the transparent sheet on which the ink-receiving layer is not stacked is exposed.

5. A recorded matter according to claim 3 , wherein the image support further includes a primer layer, and

wherein the recorded matter has the layered structure in which the image support, the primer layer, the ink-receiving layer, and the transparent sheet are sequentially stacked.

6. A recorded matter according to claim 5 , wherein the image support and the primer layer are in abutment with each other, and

wherein the recorded matter has the layered structure in which the primer layer and the ink-receiving layer are in abutment with each other.

7. A transferring material according to claim 1 , wherein the resin dispersion-type pigment comprises pigment particles coated with a (meth)acrylate-based copolymer having an acid value of 100 mgKOH/g or more and 160 mgKOH/g or less.

8. A transferring material according to claim 1 , wherein a coating weight after the ink-receiving layer is dried is 8 g/m 2 or more and 25 g/m 2 or less in terms of solid content.

9. A recorded matter comprising:

an image support on which an image is supported; and

a transferring material as recited in claim 2 on which the image is recorded,

wherein the recorded matter has a layered structure in which the image support, the ink-receiving layer, the transparent sheet, the releasing layer, and the base material sheet are sequentially stacked.

10. A recorded matter according to claim 9 , wherein the base material sheet and the releasing layer are released, and a surface of the transparent sheet on which the ink-receiving layer is not stacked is exposed.

11. A recorded matter according to claim 9 , wherein the image support further includes a primer layer, and

wherein the recorded matter has the layered structure in which the image support, the primer layer, the ink-receiving layer, and the transparent sheet are sequentially stacked.

12. A recorded matter according to claim 11 , wherein the image support and the primer layer are in abutment with each other, and

wherein the recorded matter has the layered structure in which the primer layer and the ink-receiving layer are in abutment with each other.

13. A recorded matter comprising:

an image support on which an image is supported; and

a transferring material as recited in claim 7 on which the image is recorded,

wherein the recorded matter has a layered structure in which the image support, the ink-receiving layer, the transparent sheet, the releasing layer, and the base material sheet are sequentially stacked.

14. A recorded matter according to claim 13 , wherein the base material sheet and the releasing layer are released, and a surface of the transparent sheet on which the ink-receiving layer is not stacked is exposed.

15. A recorded matter according to claim 13 , wherein the image support further includes a primer layer, and

wherein the recorded matter has the layered structure in which the image support, the primer layer, the ink-receiving layer, and the transparent sheet are sequentially stacked.

16. A recorded matter according to claim 15 , wherein the image support and the primer layer are in abutment with each other, and

wherein the recorded matter has the layered structure in which the primer layer and the ink-receiving layer are in abutment with each other.

17. A recorded matter comprising:

an image support on which an image is supported; and

a transferring material as recited in claim 8 on which the image is recorded,

wherein the recorded matter has a layered structure in which the image support, the ink-receiving layer, the transparent sheet, the releasing layer, and the base material sheet are sequentially stacked.

18. A recorded matter according to claim 17 , wherein the base material sheet and the releasing layer are released, and a surface of the transparent sheet on which the ink-receiving layer is not stacked is exposed.

19. A recorded matter according to claim 17 , wherein the image support further includes a primer layer, and

wherein the recorded matter has the layered structure in which the image support, the primer layer, the ink-receiving layer, and the transparent sheet are sequentially stacked.

20. A recorded matter according to claim 19 , wherein the image support and the primer layer are in abutment with each other, and

wherein the recorded matter has the layered structure in which the primer layer and the ink-receiving layer are in abutment with each other.
