Abstract

PURPOSE: To obtain a writing ink having excellent light resistance, weather resistance and abrasion resistance, by mixing a volatile organic solvent with a pigment, a synthetic resin soluble in said solvent, and a dispersion agent, and making the mixture to a uniform solution.
CONSTITUTION: The objective ink is prepared by adding 10W50wt% pigment (e.g. titanium white) to 25W80% volatile organic solvent (e.g. xylene), and further adding 1W30% synthetic resin (e.g. rosin-modified maleic acid resin) and 2W6% dispersing agent (e.g. a polycarboxylic acid surface active agent) to the mixture. The writing utensils for the ink are preferably particular ones suitable to the above quick-drying ink.
