Abstract

PURPOSE:To obtain the titled recording material having the following requirements or characteristics, that is the least abrasion of printing elements, a high durability and with no remaining residual substances, giving a clear recorded picture without blots etc. and an excellent head-matching property by a method wherein a high- grade fatty metallic salts with a specific melting point are contained in a color developing layer. CONSTITUTION:In the color forming layer having principal ingredients of (A) a colorless or a light-colored color forming material (example: crystal violet lactone or the like), (B) a developing substance with which a color forming material is thermally color developed (example: alpha-naphthol or the like), and (C) high-grade fatty acid metallic salts having a melting point of 200-300 deg.C [example: stearic acid lithium (or barium) or the like], desirably 0.2-0.3 multiplying ratio by weight (against the color forming material) is contained. These ingradients are applied on the basic material together with the bonding agent such as polyvinyl alcohol or the like.
