PROBLEM TO BE SOLVED: To improve the heat-resistance, and at the same time, prevent a blocking phenomenon from being generated by containing a specified weight % or more of polyarylate having a repeating unit which is represented by a specified structural formula, in a heat-resistant protective lubricating layer. SOLUTION: In a heat-resistant protective lubricating layer, 5 wt.% or more of polyarylate having a repeating unit represented by the formula is contained. (In the formula, R1, R2, R3 and R4 each independently are selected from the group consisting of a hydrogen atom, a halogen atom, a hydrocarbon radical, a nitro group and an alkyl halide group. The hydrocarbon group is selected from aliphatic groups and aromatic groups of which the number of carbon atoms is 1-20. X is selected from the group consisting of a signal bond, an oxygen atom, a sulfur atom, an alkylene group, an alkylidene group, and a cycloalkylene group or the like.) A heat-transfer heat-sensitive recording sheet having the heat-resistant protective lubricating layer containing such polyarylate is excellent in heat-resistance, and is excellent in the heat-resistance of an image as well at the time of a printing, and in addition, can improve a storage stability under a high temperature high humidity environment, without generating blocking. |
