THERMAL TRANSFER SHEET
Document Type and Number:
WIPO Patent Application WO/2012/017564
Kind Code:
A1
Abstract:
A thermal transfer sheet that is resistant to rupturing even when subjected to high thermal energy, and is exceptionally suited to high-speed printing, is provided by imparting flexibility and heat resistance to a primer layer constituting part of the thermal transfer sheet. The thermal transfer sheet has a thermally transferable colorant layer formed on one face of a substrate sheet, and a heat-resistant slipping layer formed on the other face of the substrate sheet via a primer layer. The thermal transfer sheet is characterized in that the primer layer contains at least a polyvinyl-alcohol-based resin and a crosslinking agent.
