WATER-SOLUBLE RESIN, PROCESS FOR ITS PRODUCTION AND WATER-SOLUBLE RESIN COMPOSITION |
摘要 |
<p>A water-soluble resin composition comprising a water-soluble resin and a colorant, which copolymer has a weight average molecular weight of at least 8,000 and is prepared by polymerizing an ethylenically unsaturated carboxylic acid monomer and a monomer copolymerizable therewith in the presence of an alcoholic hydroxyl group-containing water-soluble high polymer or a copolymerizable surface active agent to give a copolymer having an acid value in the range of 5 to 120 and then neutralizing the thus-obtained copolymer with a basic, exhibits a reduced viscosity change when it is stored for a long period, and is useful as an aqueous ink capable of giving an image having good dot reproducibility and good abrasion resistance.</p> |
