A thermosensitive recording material suited for use in direct thermal imaging by means of an information-wise energized heating element, said recording material containing a thermosensitive recording layer of which the optical density is changed by heat, characterized in that said recording layer is coated with a protective transparent resin layer essentially consisting of a polycarbonate or copolycarbonate derived from one or more bisphenols, wherein at least 25 mole % of said bisphenols consists of a bis-(hydroxyphenyl)-cycloalkane corresponding to following general formula (I): <IMAGE> (I) wherein: each of R1, R2 , R3, and R4 (same or different) represents hydrogen, halogen, a C1-C8 alkyl group, a substituted C1-C8 alkyl group, a C5-C6 cycloalkyl group, a substituted C5-C6 cycloalkyl group, a C6-C10 aryl group, a substituted C6-C10 aryl group, a C7-C12 aralkyl group, or a substituted C7-C12 aralkyl group, and X represents the atoms necessary to complete a 5- to 8-membered alicyclic ring, which either carries at least one C1-C6 alkyl group or at least one 5- or 6-membered cycloalkyl group, or carries a fused-on 5- or 6-membered cycloalkyl group.
