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 for transferring an image to a receptor element, the image transfer article comprising:
an image receiving surface configured to receive an image; and
a melt transfer portion having a melt transition temperature in the range of 50° C. to 250° C.;
wherein upon application of the image transfer article on the receptor element and upon application of heat, the melt transfer portion is configured to adhere the image receiving surface to the receptor element; and
wherein the image transfer article is configured to receive an image at the image receiving surface in the absence of a support layer that does not transfer to the receptor element.
2. The image transfer article of claim 1 , further comprising a pigment in at least one of the image receiving surface and the melt transfer portion providing opacity.
3. The image transfer article of claim 1 , further comprising a layer having a pigment providing opacity.
4. The image transfer article of claim 3 , wherein the layer having the pigment comprises a layer between the image receiving surface and the melt transfer portion.
5. The image transfer article of claim 3 , wherein the layer having the pigment is thermoplastic.
6. The image transfer article of claim 3 , wherein the layer having the pigment is thermosetting.
7. The image transfer article of claim 3 , wherein the layer having the pigment has a thickness between about 0.5 mils to about 2.5 mils.
8. The image transfer article of claim 1 , wherein the image receiving surface is heat sealing, in that upon application of a predetermined level of heat, the image receiving surface effectively encapsulates colorants of an image printed thereon.
9. The image transfer article of claim 1 , wherein the melt transfer portion comprises at least one of ethylene vinyl acetate, ethylene acrylic acid, and polyurethane.
10. An image transfer article for providing an image on a receptor element, the image transfer article comprising:
an image receiving surface; and
a melt transfer portion having a melt transition temperature in the range of 50° C. to 250° C.;
wherein upon application of the image transfer article on the receptor element and upon application of heat, the melt transfer portion is configured to adhere the image receiving surface to the receptor element; and
wherein the image receiving surface is configured to receive an image after the image transfer article is adhered to the receptor element.
11. The image transfer article of claim 10 , further comprising a pigment in at least one of the image receiving surface and the melt transfer portion providing opacity.
12. The image transfer article of claim 10 , further comprising a layer having a pigment providing opacity.
13. The image transfer article of claim 12 , wherein the layer having the pigment comprises a layer between the image receiving surface and the melt transfer portion.
14. The image transfer article of claim 12 , wherein the layer having the pigment is thermoplastic.
15. The image transfer article of claim 12 , wherein the layer having the pigment is thermosetting.
16. The image transfer article of claim 10 , wherein the melt transfer portion comprises at least one of ethylene vinyl acetate, ethylene acrylic acid, and polyurethane.
17. A method of transferring an image to a receptor element, the method comprising:
providing or receiving an image transfer article comprising an image receiving surface configured to receive an image and a melt transfer portion having a melt transition temperature in the range of 50° C. to 250° C.;
imaging the image transfer article in the absence of a support layer that does not transfer to the receptor element;
positioning the imaged image transfer article so that the melt transfer portion is in contact with a surface of the receptor element; and
directly or indirectly applying a predetermined level of heat to the image transfer article such that the image receiving surface and melt transfer portion concurrently transfer and adhere to the receptor element.
18. The method of claim 17 , further comprising, after positioning the imaged image transfer article and prior to applying the predetermined level of heat, placing a non-stick sheet over the image transfer article.
19. The method of claim 17 , wherein the image transfer article further comprises a pigment in at least one of the image receiving surface, the melt transfer portion, and a layer between the image receiving surface and the melt transfer portion, the pigment providing opacity.
20. The method of claim 17 , wherein the predetermined level of heat is in the range of 100° C. to 220° C.
