Abstract

The transfer material has a laminated structure in which a base material sheet, a transparent sheet, and a coloring material-receiving layer are laminated in the stated order, in which: the coloring material-receiving layer contains inorganic fine particles and a water-soluble resin; the transparent sheet contains at least two kinds of emulsions including an emulsion E 1 and an emulsion E 2 ; and the emulsion E 1 has a glass transition temperature Tg 1 of more than 50° C. and less than 90° C., the emulsion E 2 has a glass transition temperature Tg 2 of 90° C. or more and 120° C. or less, and at least the emulsion E 2 remains in a particle state in the transparent sheet.

Claims (23)

1. A transfer material having a laminated structure in which a base material sheet, a transparent sheet, and a coloring material-receiving layer are laminated in stated order, wherein:

the coloring material-receiving layer contains inorganic fine particles and a water-soluble resin;

the transparent sheet contains at least two kinds of resins including a resin E 1 and a resin E 2 ; and

the resin E 1 has a glass transition temperature Tg 1 of more than 50° C. to less than 90° C., the resin E 2 has a glass transition temperature Tg 2 of 90° C. to 120° C., and at least the resin E 2 remains in a particle state in the transparent sheet.

2. The transfer material according to claim 1 , wherein a mass ratio (E 1 /E 2 ) of the resin E 1 to the resin E 2 satisfies expression (1):

3.0≤ E 1/ E 2≤65.0  (1).

3. The transfer material according to claim 1 , wherein each of the resin E 1 and the resin E 2 , respectively, comprises a resin selected from the group consisting of an acrylic resin, a urethane-based resin, a vinyl chloride-based resin, a vinyl acetate-based resin, an ethylene/vinyl acetate-based resin, a polyamide resin, a polyester resin, and a polyolefin resin.

4. The transfer material according to claim 1 , wherein the resin E 1 comprises an acrylic resin and the resin E 2 comprises a urethane-based resin.

5. A recorded matter comprising:

an image support, a coloring material-receiving layer having an image recorded thereon, and a transparent sheet, which are laminated,

wherein the image is recorded on a surface of an ink-receiving layer, and the surface is in contact with the image support, and

wherein the coloring material-receiving layer and the transparent sheet are transferred from the transfer material of claim 1 .

6. The recorded matter according to claim 5 , wherein a part of or entirety of the resin E 2 in the transparent sheet of the recorded matter forms a film.

7. The recorded matter according to claim 5 , wherein the image recorded on the coloring material-receiving layer of the transfer material is a reverse image.

8. The recorded matter according to claim 5 , wherein the image recorded on the coloring material-receiving layer of the transfer material is formed with a pigment ink.

9. The recorded matter according to claim 5 , wherein the image recorded on the coloring material-receiving layer of the transfer material is formed by an inkjet system.

10. A method of manufacturing a recorded matter in which an image support, a coloring material-receiving layer having an image recorded thereon, and a transparent sheet are laminated, the method comprising:

a step 1 of recording an image on the coloring material-receiving layer of the transfer material according to claim 1 ;

a step 2 of thermally pressure-bonding the transfer material, in which the image has been recorded on the coloring material-receiving layer, onto the image support from a side closer to the coloring material-receiving layer; and

a step 3 of peeling the base material sheet from the transfer material to obtain the recorded matter in which the coloring material-receiving layer having the image recorded thereon and the transparent sheet are laminated in the stated order.

11. The method according to claim 10 , wherein:

at a time of the thermally pressure-bonding in the step 2, a part of or entirety of the resin E 2 in a transfer portion of the transfer material is formed into a film, and at least the resin E 2 in a non-transfer portion of the transfer material remains in the particle state; and

in the step 3, the recorded matter is obtained by peeling the base material sheet from the transfer material while maintaining a state in which the part of or the entirety of the resin E 2 in the transfer portion is formed into the film, and the resin E 2 in the non-transfer portion remains in the particle state.
