Abstract
A heat transfer recording sheet comprising a base film, a layer of heat transferable coloring material on one side of the base film and a heat resistant layer on the other side of the base film, wherein said heat resistant layer is formed by curing a mixture comprising a compound of the formula: ##STR1## wherein each of R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 is an acryloyl group or a methacryloyl group, and R.sup.6 is an acryloyl group, a methacryloyl group, an alkyloyl group or a hydrogen atom, and a compound of the formula: ##STR2## wherein each of R.sup.7 and R.sup.8 is an acryloyl group or a methacryloyl group, each of R.sup.9 and R.sup.10 is a hydrogen atom, an alkyl group or an aryl group, and each of rings A and B is a benzene ring which may have a lower alkyl group and/or a halogen atom as a substituent, and n is an integer of from 1 to 9, and/or a compound of the formula: ##STR3## wherein each of R.sup.11, R.sup.12 and R.sup.13 is an acryloyl group or a methacryloyl group, and m is an integer of from 0 to 5.
