Abstract

PURPOSE: To provide a water-based blot-free writing utensil capable of keeping its writing chracteristics stably for a long time without clogging of the pen point, and containing a novel water-based ink obtained by finely dispersing a water- insoluble pigment in an aqueous emulsion of a synthetic resin, etc.
CONSTITUTION: The title writing utensil containing a water-based ink obtained by dispersing (A) a water-insoluble pigment (pref. processed dye or pigment such as carbon black, etc.) finely in (B) an aqueous emulsion of a natural or a synthetic resin (pref. a resin latex prepared by the emulsion polymerization of an acrylic monomer), and adding (C) an aqueous medium (e.g. an emulsifier, protective) colloid, and water) to the dispersion. The amounts of the resin (B) and the pigment (A) are pref. 5W50pts. and 2W20pts., respectively, based on 100pts.wt. of the water-based ink.
USE: Suitable for marking pen, etc.
