Abstract

PURPOSE:To obtain a coloring matter dispersed liquid for coloration-preventive heat-sensitive recording paper, which contains lactone type coloring matters, such as phthalide type coloring matters, etc., and metallic ion blocking agent. CONSTITUTION:100 weight parts of lactone type coloring matters such as phthalate type coloring matters (such as, malachite green lactone, etc.) which are expressed by the formula (a-d: C or 1 or 2 pieces of N and C; a-b, b-c and c-d combinations: other type of cyclic formations may used; X, Y: benzene, naphthalene, aromatic heterocyclic ring), (di) azophthalate type coloring matter and fluorene type coloring matter, etc., together with water-soluble high molecular compound, such as PVA, etc., or surface active agent and 0.1-50wt. parts of metallic ion blocking agent (such as, ethylenediamine acetate, etc.), are finely pulverized in a wet-type grinding mill, such as a ball mill, to reduce particle size to several mu).
