摘要： PURPOSE:To prevent fog and to enhance the storage stability of a developed color image, in a thermal recording material containing a leuco dye and a developer as main components, by using a double salt represented by a specific chemical formula and having an m.p. within a specific temp. range as a developer. CONSTITUTION:As a developer of a thermal recording material, a double salt represented by general formula (wherein n is an integer of 1 or 2, each of aromatic rings may have one or more group selected from an alkyl group, a cycloalkyl group, an aralkyl group and an aryl group and A is a nitrogen- containing org. basic compound) is used. This double salt has an m.p. within the range of 70-250 deg.C and, as the nitrogen-containing basic compound, an amine compound, a hydrazine compound or a guanidine compound is used. The double salt is obtained by reacting 2mol of a chlorosalicylic acid derivative such as 3-chlorrosalicylic acid, 1mol of boric anhydride and 1mol of the nitrogen- containing org. basic compound corresponding to one mol of basic nitrogen.

摘要： PURPOSE:To form a high-density image, prevent a fog on an image, and obtain a resistance to light and resistance to heat by using a salt of zinc polydisalicylate as a color developed in a recording material containing a leuco dye and the color developer as main components. CONSTITUTION:A recording material can be obtained by a normal method by mainly containing a leuco dye shown by a formula I (R -R represent hydrogen atom or the like, or adjacent two groups may form a carbon ring) as a color forming material and a salt of zinc polydisalicylate as a color developer. For example, a pressure-sensitive recording material can be formed in the following manner. In producing CF paper, a water dispersion liquid of a color developer is prepared by mixing and grinding the color developer, such a binder as a water-soluble polyvinyl alcohol, water, a rubber latex, and the like, and this is applied on paper as a substrate and dried. On the other hand, in producing CB paper, an emulsion of a leuco dye is similarly prepared by mixing the leuco dye, an emulsifying agent, and water, and this is applied on paper as a substrate and dried.
