PURPOSE: To provide the titled compsn. excellent in adhesion and printability, by employing as a vehicle component a resin solution prepared by adding ammonia or an amine to a particular acrylic copolymer dissolved in an aqueous medium.

CONSTITUTION: 1W10wt% carboxyl group-contg. vinyl monomer (e.g., acrylic acid), 3W40wt% vinyl monomer having in the molecule polyalkylene oxide group of the formula (wherein R is H, methyl; n is 2W50) [e.g., polyethylene glycol mono(meth)acrylate], 0W30wt% vinyl monomer having an OH group [e.g., 2- hydroxyethyl (meth)acrylate], and other vinyl monomer copolymerizable therewith are subjected to soln. polymn. in the presence of a polymn. initiator to yield an acrylic copolymer. Said copolymer is neutralized by adding ammonia or an amine, and dissolved in an aqueous medium to yield a resin soln. as a vehicle component. Colorants, fillers, etc. are incorporated in said resin soln.
