Abstract

A heat transfer label is disclosed. The heat transfer label comprises a special heat stable release which strongly adheres to the carrier, offers a highly ink and adhesive wettable surface, stays intact under heat transfer bonding conditions, releases easily, leaves no contamination on the transfer or fabric, and enables durable replication of the release surface finish onto the resultant transfers.

First claim

What is claimed is:

1. A heat transfer label for application to an item, comprising:
a carrier;
a release layer on the carrier surface;
an ink design layer;
an adhesive layer in registration with the ink design layer; and
wherein the release layer comprises a heat stable film forming organic composition which comprises a thermoset or chemically crosslinked composition, a surface active chemistry component comprising a multi-segmented or branched macromere, pre-polymer or polymer with both matrix-compatible and matrix-incompatible sections, and a dispersion of fine, heat stable solid phase components.

2. The heat transfer label of claim 1 , wherein the carrier comprises a plastic sheet, film, or paper stock.

3. The heat transfer label of claim 1 , wherein the heat stable film forming organic composition constitutes a matrix or body of the release layer.

4. The heat transfer label of claim 1 , wherein the ink design layer is a single color ink design layer.

5. The heat transfer label of claim 1 , wherein, the release layer has a composition of 70-85 at % carbon, 1-10 at % nitrogen, 10-25 at % oxygen, and 0-10 at % silicon.

6. The heat transfer label of claim 1 , wherein the release layer is applied to a front and a back of the carrier for double-sided release.

7. A heat transfer label for application to an item, comprising:
a plastic film carrier;
a release layer on the carrier surface;
a multi-color ink design layer; and
an adhesive layer in registration with the ink design layer; and
wherein the release layer comprises a heat stable film forming organic composition which comprises a thermoset or chemically crosslinked composition, a surface active chemistry component comprising a multi-segmented or branched macromere, pre-polymer or polymer with both matrix-compatible and matrix-incompatible sections, and a dispersion of fine, heat stable solid phase components.

8. The heat transfer label of claim 7 , wherein the heat stable film forming organic composition constitutes a matrix or body of the release layer.

9. The heat transfer label of claim 7 , wherein the surface active chemistry component forms a structural linkage with the release layer matrix and has a uniform distribution over the surface region of the release layer matrix.

10. The heat transfer label of claim 9 , wherein the surface active chemistry component forms a structural linkage with the release layer matrix and has a uniform distribution over a surface region of the release layer matrix.

11. The heat transfer label of claim 10 , wherein the dispersion of fine, heat stable solid phase components are distributed in the release layer matrix and its surface.

12. The heat transfer label of claim 11 , wherein the release layer is applied to the carrier surface via sheet-fed printing or coating and web printing or coating.

13. The heat transfer label of claim 9 , wherein the dispersion of fine, heat stable solid phase components are distributed in the release layer matrix and its surface.

14. The heat transfer label of claim 7 , wherein the release layer is applied to the carrier surface via sheet-fed printing or coating and web printing or coating.

15. The heat transfer label of claim 7 , wherein the release layer is applied to a front and a back of the carrier for double-sided release.

16. A heat transfer label for application to an item, comprising:
a plastic film carrier;
a release layer on the carrier surface;
a multi-color ink design layer;
an adhesive layer in communication with the ink design layer; and
wherein the release layer comprises a heat stable film forming organic composition which constitutes a matrix or body of the release layer and comprises a thermoset or chemically crosslinked composition, a surface active chemistry component comprising a multi-segmented or branched macromere, pre-polymer or polymer with both matrix-compatible and matrix-incompatible sections, and a dispersion of fine, heat stable solid phase components which are distributed in the release layer matrix and its surface.

17. The heat transfer label of claim 16 , wherein the surface active chemistry component forms a structural linkage with the release layer matrix and has a uniform distribution over the surface region of the release layer matrix.

18. A release functionalized carrier suitable for heat transfer applications comprising:
a heat stable film forming organic composition which comprises a thermoset or chemically crosslinked composition;
a surface active chemistry component comprising a multi-segmented or branched macromere, pre-polymer or polymer with both matrix-compatible and matrix-incompatible sections; and
a dispersion of fine, heat stable solid phase components.
