Title:
METHOD FOR PRODUCING COLOR DEVELOPING COMPOSITION FOR HEAT-SENSITIVE RECORDING, COLOR DEVELOPING COMPOSITION FOR HEAT-SENSITIVE RECORDING, AND HEAT-SENSITIVE RECORDING MATERIAL
Document Type and Number:
Japanese Patent JP2018016000
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat-sensitive recording material capable of forming an image part which causes little ground fogging and has good color developing properties and excellent preservability (especially alcohol resistance and water resistance), and to provide a color developing composition for heat-sensitive recording which achieves the same and a method for producing the same.SOLUTION: There is provide a method for producing a color developing composition for heat-sensitive recording, which comprises a step of reacting 4,4'-dihydroxydiphenylsulfone with an aralkyl halide compound in an aqueous solvent having a water content of 96 mass% or more. Further, the color developing composition for heat-sensitive recording comprises 100 pts.mass of 4-aralkyloxy-4'-hydroxydiphenylsulfone and 0.2 to 10 pts.mass of a compound represented by the following general formula (I). [where, Rrepresents an aralkyl group which may have a substituent, Rand Reach represent an aralkyl group which may have a substituent, and one of n and m is 1 and the other is 0].SELECTED DRAWING: None
