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.

Disclosed herein is an image receiving sheet for dye transfer-type thermal transfer recording, comprising:

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, a heat transferable ink layer formed on one side of the base film and a heat resistant lubricating layer formed on the other side of the base film, wherein the heat resistant lubricating layer is formed by coating on the base film a coating solution containing at least a binder resin and at least two mutually reactive modified silicone oils, and then reacting the mutually reactive modified silicone oils.

A thermal transfer recording sheet comprising a base film, a heat transferable ink layer formed on one side of the base film and a heat resistant lubricating layer formed on the other side of the base film, wherein the heat resistant lubricating layer contains fine elastomer particles.

An image receiving sheet for thermal transfer recording, which comprises a substrate and an image receiving layer formed on the substrate, wherein the image receiving layer comprises, as the main component, a polyvinyl acetal resin of the following formula (I): ##STR1## wherein k, l, m and n represent percentages of the respective structural units in the formula within ranges of 50&lt;k+l&lt;85, 0.ltoreq.k&lt;85, 0.ltoreq.l&lt;85, 10&lt;m&lt;50 and 0&lt;n&lt;30, and R.sup.1 and R.sup.2 are different from each other and each represents a hydrogen atom, a substituted or unsubstituted alkyl group, an aryl group, an alkenyl group or a vinyl group substituted by an aryl group, provided that when R.sup.1 is an unsubstituted alkyl group, l.noteq.0.
