<p>PURPOSE:To provide a solid correcting material capable of correcting the written marks of both water-based and oil-based inks, by compounding a condensate of a specific sugar alcohol and an aromatic aldehyde, a hydrogenated castor oil, a cycloaliphatic hydrocarbon solvent having a specific boiling point range, a film-forming resin and a white pigment. CONSTITUTION:The objective solid correcting material is composed of (A) the condensate of a 5-7-hydric sugar alcohol and an aromatic aldehyde (e.g. monobenzylidene xylitol) and/or hydrogenated castor oil, (B) a cycloaliphatic hydrocarbon solvent having a boiling point of 100-170 deg.C (e.g. methylcyclophexane, isopropylcyclohexane, etc.), (C) a film-forming resin (e.g. acrylic resin, alkyd resin, etc.) and (D) a white pigment (preferably titanium dioxide). The weight ratios of A:B:C:D are preferably (0.5-10):(30-60):(5-20):(30-70).</p> |
