PROBLEM TO BE SOLVED: To provide a heat sensitive recording material, the poor hardening of which at the employment of a hardener, the migration of a low molecular weight siloxane compound to an ink layer of which and the self-adhesion of which to a thermal head, the pollution of the thermal head by which or the like, during a high temperature usage are prevented from occurring and the back side layer of which has excellent lubricity. SOLUTION: The heat sensitive recording material has the back side layer including an ultraviolet curing type urethane-based polymer, which has a polysiloxane segment derived from a polysiloxane compound represented by formula and an unsaturated bond derived from a glycerin mono-allyl ether or the like in a molecular chain. |
