Abstract
A heat sensitive recording material comprising a substrate having sequentially thereon a heat sensitive recording layer and a protective layer, 1) wherein the protective layer contains an aqueous silicone modified polymer. It is desirable this aqueous silicone modified polymer is used together with an aqueous binder, and a crosslinking agent which can cause a crosslinking reaction with them is desirably used. 2) The protective layer contains a silicone modified polymer having a Tg (glass transition point) of 60.degree. C. or more. In the heat sensitive recording materials of 1) and 2), the silicone modified polymer is desirably a silicone graft polymer, silicone block polymer, silicone modified acrylic polymer and the like, and particularly, the silicone graft polymer is desirably a silicone graft acrylic polymer and the like.
