Patent ID: 7008692

Claim:
A protective layer transfer sheet comprising: a substrate sheet; a heat-resistant slip layer provided on one side of the substrate sheet; and a thermally transferable protective layer releasably provided on at least a part of the surface of the substrate sheet opposite to the heat-resistant slip layer side, the protective layer comprising a main protective layer and an adhesive layer provided in that order from the substrate sheet side, the adhesive layer containing from 3 to 10% of microsilica based on a resin solid matter in the adhesive layer, the coefficient of friction between the surface of the protective layer and the surface of an image-receiving sheet before thermal transfer being 0.05 to 0.5 in terms of μ 0 (coefficient of static friction) and μ (coefficient of dynamic friction) with the value of μ 0 /μ being 1.0 to 1.5.
