Abstract
Abstract A water soluble or alcohol soluble printing ink composition comprising: (A) 10 to 50% by weight of a resin, said resin being prepared by radical - polymerizing a mixture of (a) an unsaturated aromatic hydrocarbon, (b) a monoacrylate or monomethacrylate of a polyhydric alcohol and (c) an A,B- unsaturated carboxylic acid in the presence of an organic solvent, said resin having an acid value of 5 to 150 and a hydroxyl value of 30 to 120; (B) 30 to 80% by weight of a solvent (C) 1 to 40% by weight of a pigment or dye.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
A water soluble or alcohol soluble printing ink composition comprising: (A) 10 to 50% by weight of a resin, said resin being prepared by radical-polymerizing a mixture consisting essentially of (a) an unsaturated aromatic hydrocarbon, (b) a monoacrylate or monomethacrylate of a polyhydric alcohol and (c) an α,β-unsaturated carboxylic acid in the presence of an organic solvent, said resin having an acid value of 5 to 150 and a hydroxyl value of 30 to 120; (B) 30 to 80% by weight of a solvent selected from the group consisting of an alcohol having 1 to 10 carbon atoms, a mixed solvent of alcohol aqueous solution of an alkali and an aqueous solution of an alkali; and (c) 1 to 40% by weight of a pigment or die.
Claim 2
Dependent Claim
127 words
