THERMOSENSIBLE RECORDING MATERIAL

Japanese Patent JP3683679

B2

PROBLEM TO BE SOLVED: To improve life conservation, and enhance sufficiently the coloring density of coloring images, and further provide a high photosensitive property through light having a relatively long wavelength by allowing a diazo compound to be a compound expressed by a specific formula, and including the diazo compound in microcapsules.
SOLUTION: As a diazo compound, the compound is expressed by a formula, where in R1 shows an alkyl sulfienyl group, an aryl sulfinyl group, an alkyl sulfinyl group, an aryl sulfinyl group, an alkyl sulfonyl group, an aryl sulfonyl group, a sulfamory group, an alkoxy carbonyl group, a carbamoyl group, a carboxyl group, an acyl group, or cyano group, R3, R4 respectively show a hydrogen atom, an alkyl group, or aryl group, R2, R5 or R6 respectively show a hydrogen atom, an alkyl group, an aryl group, an alkoxy group, or a halogen atom, X- shows an anion, and R2 and R3, R4 and R5, and R3 and R4 can be combined for preferably forming a cycle, and the diazo compound is contained in capsules.
