A thermal transfer recording sheet comprising a base film, a thermally transferable ink layer formed on one side of the base film, a heat resistant lubricating layer formed on the other side of the base film, wherein the total concentration of alkali metal ions and alkaline earth metal ions contained in the heat resistant lubricating layer is within a range of at most 4 .mu.g/cm.sup.2.

Thermal transfer recording sheet

The disclosure describes a thermal transfer recording sheet comprising a base film, a colorant layer provided on one side of said base film and containing a heat-transferable dye, and a heat-resistant lubricating layer provided on the other side of said base film and containing a thermoplastic resin having a glass transition point of not less than 50.degree. C., an amino-modified silicone oil and a carboxy-modified silicone oil.

An image receiving sheet for thermal transfer recording is described. The sheet contains a substrate and an image receiving layer formed thereon for receiving a sublimable dye. The image receiving layer contains, as its main component, a product formed by thermosetting a composition of an active hydrogen-containing resin, a modified silicone resin, a silicone oil and a polyfunctional isocyanate compound.

Image receiving sheet for thermal transfer recording

A thermal transfer recording sheet comprising a substrate and an image-receiving layer formed thereon, which is thermally transferable onto a record sheet, wherein the image-receiving layer comprises a transparent receptive layer and a white opacifying layer laminated in this order on the substrate, and the opacifying layer contains a plasticizer.

A thermal transfer recording sheet comprising a base film and an ink layer comprising at least a heat transferable colorant and a binder resin, formed on one side of the base film, wherein the binder resin is a phenoxy resin having repeating structural units of the following formula (I): ##STR1## wherein X is a bivalent group represented by ##STR2## --O--, --S--, --SO-- or --SO.sub.2 --, each of R.sup.1 and R.sup.2 is a hydrogen atom, an alkyl group or an aryl group, R.sup.3 is an alkylene group, and each of benzene rings A and B may have an alkyl group or a halogen atom as a substituent.

An image receiving sheet for thermal transfer recording, which comprises a substrate and an image receiving layer formed thereon for receiving a sublimable dye, wherein the image receiving layer comprises, as the main component, a product formed by thermosetting a composition comprising an active hydrogen-containing resin, a silicone resin, a silicone oil and a polyfunctional isocyanate compound.
