PURPOSE:To improve the storing stability, by containing an aqueous polyester polyurethane resin into one of a heat-sensitive coloring layer or an intermediate layer in a heat-sensitive recording material containing an electron donative component and an electron receiving component. CONSTITUTION:A supporting material, a heat-sensitive coloring layer mainly composed of an electron donative component and an electron receiving layer, and if required, an intermediate layer and a protection layer are laminated in this order. An aqueous polyester polyurethane resin is contained into one of the heatsensitive coloring layer or the intermediate layer. Consequently, excellent water-proof performance and anti-chemical performance can be achieved. |
