<p>PURPOSE:To obtain the title composition giving an easily erasable written mark on an impermeable writing face, by compounding a pigment, a lower alcohol, a specific fatty acid ester, tributoxyethyl phosphate, etc. CONSTITUTION:The objective composition is produced by compounding (A) a pigment, (B) a lower alcohol (e.g., propanol), (C) a resin soluble in the component B (e.g., polyvinyl butyral), (D) a fatty acid ester (e.g., hexadecyl isooctanoate) which is an ester of (i) a >=8C monocarboxylic acid and (ii) a >=8C aliphatic monohydric alcohol and (E) tributoxyethyl phosphate. The amounts of the components A, B, C, D and E are preferably 2-10wt.%, 72-85wt.%, 2-10wt.%, 3-8wt.% and 1-4wt.%, respectively.</p> |
