摘要：
A heat-sensitive recording unit formed by supporting a methine-type chromogenic reactant and oxidizing organic compound on a base. A color production sensitivity regulator may further be supported on the base. It is also feasible to add a quaternary ammonium salt, tertiary alkanol amine or water-soluble ion sequestering agent for avoiding undesirable color production of the methine-type chromogenic reactant. The ammonium salt, amine or ion sequestering agent may be added upon forming the methine-type chromogenic reactant into an aqueous suspension in order support the methine-type chromogenic reactant on the base.
