<p>PURPOSE:To obtain the titled composition suitable for writing on glass, woody products, plastics, paper, cloth or stone materials, having excellent long-term stability, water resistance and light resistance, containing a specific colorant, an alcohol-soluble resin and an ethanol solvent. CONSTITUTION:The aimed composition containing (A) preferably 12-40wt.% colorant obtained by reacting a cationic surface active agent shown by the formula (X is halogen; R is 12-18C aliphatic hydrocarbon; sum of m and n are 2-15) with metallic complex acidic dye (preferably C.I. Acid Black 52, C.I. Acid Black 52:1, C.I. Acid Black 107, 118, 119 and 155), (B) preferably 1-30wt.% alcohol-soluble polymer (e.g. ketone polymer) and (C) preferably 40-85wt.% alcohol solvent comprising ethanol as a main solvent component.</p> |
