Abstract

PURPOSE: To obtain an ink for a ball-point pen, readily erasable by an eraser without discoloration or damage of paper, by dissolving a gelation product prepared by kneading a vinyl chloride resin, its plasticizer and a pigment of specified particle size, in a low-boiling solvent.
CONSTITUTION: A gelation product prepared by kneading a vinyl chloride resin, a plasticizer for said resin, a pigment of particle size of 0.01W5μ, and, if necessary, a stabilizer for said resin, is dissolved in a low-boiling solvent of boiling pt. ≤200°C. Because the vinyl chloride resin has no double bond except for the terminal group, it is not crosslinked witn time, and no written line is firmly bonded with cellulose in paper. Therefore it is possible to erase the written line by an eraser.
