摘要： PURPOSE:To improve thermally responding properties and the can-stability of a coloring picture image by having a heat sensitive coloring layer containing a basic colorless dye and a specific organic developer. CONSTITUTION:A recording paper has a heat sensitive coloring layer containing a colorless or light-colored basic colorless dye and an organic developer and contains as said organic developer bis-(3-phenyl-4-hydroxyphenyl)sulfone or bis-(2-methyl-4-hydroxy-5-cyclohexylphenyl)sulfone. Said compound is synthesized by oxidation of bis-(4-hydroxyphenyl)sulfide compound by the use of oxidizing agent and hydrogen peroxide, hydroperoxide, osmium oxide, etc., are used as such agent. Also, triphenylmethane dye, fluorane dye, azaphthalide dye, fluorene dye, etc., are preferable as said basic colorless dye. In this case, 3-12 parts organic developer, 3-12 parts sensitizer, and 1-20 parts filler are used for 1 part basic colorless dye, and the suitable amount of binder is 10-25% in the whole solid content. Thus, it is possible to obtain a heat sensitive recording body, when the application liquid of said composition is applied to an arbitrary base.
