ABSTRACT:
A dyesheet is provided for thermal transfer printing, comprising a base sheet having a thermal transfer dye layer on one surface, and on the other a heat resistant backcoat comprising a crosslinked reaction product of radically polymerising a compound having a plurality of polymerisable unsaturated groups per molecule, wherein the backcoat is formulated to minimise scratching of the print during printing. The formulation comprises a) a compound having a single radically polymerisable unsaturated group which is copolymerised with the compound having a plurality of polymerisable unsaturated groups per molecule, and b) a multivalent metal salt of a long chain alkyl or alkylphenyl phosphate ester as slip agent. These two factors (a & b) work together, and if either is omitted, relief from scratching does not generally occur.
