PURPOSE:To enhance plasticizer resistance, diazo developing liquid resistance and preservability, by using a specified organometallic compound and a specified phenol compound in combination as a color reaction agent. CONSTITUTION:At least one organometallic compound of general formula [I] or [II] and at least one compound of general formula [III] are used in combina tion as a color reaction agent. The compound of formula [I] may be, for exam ple, a multivalent metal salt, such as a magnesium salt and a calcium salt, of a halophthalic acid such as monomethyl ester and monoethyl ester of tetrahalophthalic acid such as 4-fluorophthalic acid and 4-chlorophthalic acid. The compound of formula [II], wherein each of ligands R2 and R3 is pyrrole, 2,4-dimethylpyrrole or the like, may be, for example, a thiocyanate of a multiva lent metal such as magnesium and calcium. The compound of formula [III] may be 1-(4-hydroxyphenoxy)-2-phenoxyethane or the like. The amount of the phenol compound is 1-1,000pts.wt. per 100pts.wt. of the organometallic com pound. |
