Abstract
Abstract There is disclosed a sublimation type thermal ink transfer recording material comprising a biaxially drawn film substrate consisting of a polyester base film and an applied primer layer of a reaction product of a polymerizable compound having carbon-carbon unsaturated bonds and a polyester, said substrate being drawn after a solution containing said reaction product is applied on the polyester film; a layer of sublimation type ink formed on said applied layer; and a slippery layer formed on the side opposite to said ink layer. This material has an ink layer which is not easily peeled off and has excellent image-forming ability.
