Abstract

PURPOSE:To obtain the captioned sheet superior in prevention of natural color forming and in waterproofing by using the ammonium salt of copolymer of styrene, butyl acrylate ester and methacrylic acid for a thermo-recording layer containing a phenolic acid material etc. as a disperser. CONSTITUTION:After a phenolic acid material (e.g. 4, 4'-isopropyl den diphenol etc.) (A) and a colorless or light-colored leuco compound (the phenolic acid material and a compound of triphenylmethane system, etc. whose color is formed under heat) (B) are dispersed separately in the ammonium water solution of the copolymer of styrene, butyl acrylate ester and methacrylic acid (it is preferable that the content of styrene is 5-50wt%, while the amount to be used is 2-10wt% in relation to thermal solid part) (C), both are mixed and a bonding agent (e.g. casein etc.) (D) is added thereto, thus the aimed sheet being obtained.
