Image transfer material and polymer composition
View Patent ↗Provided is an image transfer material, comprising a support, optionally at least one barrier layer, a melt transfer layer, and an image receiving layer. Also provided is a process for preparing the image transfer material. Further provided is a heat transfer process using the disclosed material. In the heat transfer process, after imaging, the image receiving layer and melt transfer layer are peeled away from the optionally barrier-coated support material and placed, preferably image side up, on top of a receptor element. A non-stick sheet is then optionally placed over the imaged peeled material and heat is applied to the top of the optional non stick sheet. The melt transfer layer then melts and adheres the image to the receptor element. A composition comprising: at least one self-crosslinking polymer, and at least one dye retention aid.
1. An image transfer article, comprising:
a melt transfer layer having a top surface and a bottom surface, the bottom surface positionable against a receptor element during a transfer process;
an image receiving layer having an image receiving surface configured to receive indicia or an image; and
at least one opaque layer disposed between the image receiving layer and the top surface of the melt transfer layer, the at least one opaque layer configured to provide an opaque background for at least a portion of the image and having sufficient thickness and rigidity so that the image transfer article can function independently of a support.
2. The article of claim 1 , wherein the opaque background includes a substantially white opacity provided by a white pigment or a substantially colored opacity provided by a colored pigment.
3. The article of claim 2 , wherein the white pigment comprises titanium oxide or the colored pigment comprises a pigmented resin.
4. The article of claim 1 , wherein the at least one opaque layer comprises a first and a second opaque layer.
5. The article of claim 4 , wherein the first opaque layer has a composition that is different from a composition of the second opaque layer.
6. The article of claim 1 , wherein the at least one opaque layer as a thickness between about 0.5 mils and about 2.5 mils.
7. An image transfer article, comprising:
a transfer member comprising (i) a melt transfer layer, (ii) an image receiving layer having an image receiving surface configured to receive indicia or an image, and (iii) at least one opaque layer positioned between the melt transfer layer and the image receiving layer and configured to provide an opaque background to the image and having sufficient thickness and rigidity so that the image transfer article can function independently of a support,
wherein the image transfer article is configured to transfer the received indicia or image to a receptor element without inversion or reversal of the indicia or image.
8. The article of claim 7 , wherein the opaque background includes a substantially white opacity provided by a white pigment or a substantially colored opacity provided by a colored pigment.
9. The article of claim 8 , wherein the white pigment comprises titanium oxide or the colored pigment comprises a pigmented resin.
10. The article of claim 7 , wherein the at least one opaque layer comprises a first and a second opaque layer.
11. The article of claim 10 , wherein the first opaque layer has a composition that is different from a composition of the second opaque layer.
12. The article of claim 7 , wherein the at least one opaque layer as a thickness between about 0.5 mils and about 2.5 mils.
