Title:
WATER-COMPATIBLE RESIN AND WATER-BASE PRINTING INK COMPOSITION CONTAINING THE SAME
Document Type and Number:
Japanese Patent JP3404410
Kind Code:
B2
Abstract:

PURPOSE: To obtain a water-compatible resin having excellent pigment dispersibility, solubility and applicability to water-repellent liner by randomly copolymerizing a specified dicarboxylic half-ester with a styrene monomer, an α,β-ethylenically unsaturated nitrogenous monomer and other copolymerizable α,β-ethylenically unsaturated monomers.
CONSTITUTION: 5-55wt.% at least one monomer selected from among 2-3C dicarboxylic half-esters each containing a radical-polymerizable unsaturation and represented by the formula (wherein R1 is 1-24C alkyl which may be branched; and X is a 2-3C hydrocarbon group containing a radical-polymerizable unsaturation) is randomly copolymerized with 3-94wt.% styrene monomer, 1-60wt.% α,β-ethylenically unsaturated nitrogenous monomer and 0-30wt.% other copolymerizable α,β-ethylenically unsaturated monomers at 60-170°C in the presence of a reaction initiator in a solvent in an inert gas to obtain a resin having a molecular weight of 5000-100000 and a melting point of 40-180°C.
