Abstract
PURPOSE:To obtain a pigment having a clear hue and a high tinting strength and being useful as an excellent blue pigment, by reacting phthalic acid with urea in the presence of a catalyst and a specified compound in an organic solvent. CONSTITUTION:The production of copper phthalocyanine by reacting phthalic acid and/or its derivative with urea and copper or its compound in the presence of a catalyst in an inert organic solvent is performed in the presence of a compound of the formula. Examples of said phthalic acid and/or its derivative used include those which can form a copper phthalocyanine ring, for example, phthalates, phthalimide, phthalamic acid and their salts or esters. Examples of said catalysts include molybdenum compounds, zirconium compounds and antimony oxides. Examples of said organic solvents which can be used include aromatic hydrocarbons, alicyclic hydrocarbons, aliphatic hydrocarbons, nitrobenzene and chloronaphthalene.
