Dye-donor element for use according to thermal dye sublimation transfer comprising a support having on one side a dye layer and on the other side a slipping layer, characterized in that said slipping layer comprises the cured product of a moisture-curable binder composition prepared by mixing the following components (A) and (B):(A) 30 to 99 parts by weight of at least one copolymer of olefinically unsaturated compounds having a weight-average molecular weight [Mw] of at least 1500 and containing chemically incorporated moieties capable of undergoing an addition reaction with amino groups, and(B) 1 to 70 parts by weight of organic substances containing blocked amino groups from which substances under the influence of moisture compounds having free primary and/or secondary amino groups are formed,wherein i) the copolymers of component (A) contain intramolecularly bound carboxylic anhydride moieties, with the anhydride equivalent weight of the copolymers being from 196 to 9800 and ii) the binder composition contains from 0.25 to 10 anhydride moieties for each blocked amino group.
