Abstract
Thermal transfer dyesheets are disclosed containing highly efficient back-side antistick coatings. These are particularly useful in thermal dye transfer printing materials where relatively high temperatures are used in the thermal head and where dye offset from the front of one sheet to the back of an adjacent sheet is often a problem. These coatings comprise at least one polyfluorinated resin having an acrylate functionality, and at least one more resin having an acrylate functionality to provide a crosslinked matrix.
