Summary:PURPOSE: To suppress the generation of photolytic stains generated when a diazonium compd. is photolyzed by adding aromatic carboxylic ester represented by a specific formula and the diazonium salt compd. as a core substance. CONSTITUTION: In a microcapsule adapted to an optical fixing type thermal recording material and containing a diazonium salt as a core substance, as the core substance, aromatic carboxylic ester represented by formula and a diazonium compd. are added. In the formula, R1 is a halogen atom, an alkyl group, an alkenyl group or a heterocyclic group, R2 -R6 are independently a hydrogen atom, a halogen atom, an alkenyl group or a heterocyclic group, L is -COO-, -OCO-, -COO(CR7 R8 )q - or -OCOC(CR7 CR8 )q , R7 and R8 are a hydrogen atom or a halogen atom, q is an integer of 1-10, n is an integer of 0-5, p is an integer of 2-4 and n+p is 6 or less.
