PURPOSE:To enhance image preservability by using a co-dispersion prepared by finely pulverizing an imino compound and metal soap at the same time. CONSTITUTION:In a recording material containing an aromatic isocyanate compound and an imino compound forming a color upon the reaction with said isocyanate compound at the time of heating, a co-dispersion prepared by finely pulverizing the imino compound and metal soap at the same time is used. As the metal soap used therein, a metal salt of fatty acid, resin acid or naphthenic acid is designated and, as the acid, there are caproic acid, caprylic acid, capric acid or the like. As a metal, aluminum, manganese, cobalt, lead and calcium are designated.
