Abstract
A laminated image transfer sheet, having a backing sheet, a heat release layer on said backing sheet, an ink design layer on said heat release layer, a polymer layer containing a water-dispersible polymer on said ink design layer and a lacquer mask layer on said polymer layer, is used in a dry heat transfer process to transfer an ink design to a substrate.
Claims19
A laminated image transfer sheet, comprising:
- a backing sheet;
- a heat release layer on said backing sheet;
- an ink design layer on said heat release layer;
- a polymer layer containing a water-dispersible polymer on said ink design layer;
- and
- a mask layer on said polymer layer, wherein said mask layer outlines an ink design in said ink design layer, but does not cover said ink design and allows transfer of only said heat release layer, said ink design and said polymer layer within said outlined ink design.
