PROBLEM TO BE SOLVED: To provide a heat-sensitive coloring composition for manufacturing a heat-sensitive recording material of superior coloring properties and storage properties. SOLUTION: A heat-sensitive coloring composition is composed of a development compound, a coloring compound reacted with the development compound by heating and colored and a polymer compound, both of which are dispersed in an organic solvent. In that case, a heat-sensitive coloring composition containing a compound represented by a formula and a heat-sensitive recording material manufactured by applying the heat-sensitive composition on a substrate and dried thereon can be obtained. |
