In a receiver sheet for dye-diffusion thermal transfer printing, a receiver coat of dye-receptive polymer containing a crosslinked silicone release system, is protected against loss of release function when overlying a substrate or coating containing particulate metal salts or metal oxides, by a protective polymeric interlayer comprising an acidic polymer composition selected from: a) an addition polymer in which at least 30% of its monomer molecule residues contain at least one carboxylic acid group, b) a blend of at least two addition polymers in which at least 30% of the monomer molecule residues in the blend contain at least one carboxylic acid group, c) a crosslinked addition polymer wherein the addition polymer molecules are substantially crosslinked to form an insoluble polymer matrix in the presence of excess strong organic acid.
