PURPOSE:To obtain a thermally sensitive recording material capable of high resistance against sticking, superior lubricity, excellent mold-releasing property and without any adverse effect to a thermal recording device by adding specific organic phosphor compound to a thermally sensitive color developing layer. CONSTITUTION:Alkali earth metallic salts of alkylphosphate monoester and/or alkylphosphate diester are used as specific organic phosphor compound shown by formula I and/or formula II. The recommendable types of ester are laurylphosphate ester and cerylphosphate ester. The thermally sensitive color developing layer actually used is the one of dye type, metallic salt type or wax type. Furthermore, the preferable dyes are basic dyes such as diphenylmethane dye, triphenylmethane dye. The recommendable developers are active clay and colloidal silica and are applied to papers and plastic film, then dried. Consequently, the thermally sensitive recording material is obtained which is capable of high resistance against sticking, lubricity and mold-releasing property and does not give any adverse effect to a thermally recording material. |
