Flexographic ink composition containing hydrolyzed gelatin as a binder resin

Abstract

A flexographic preprint ink composition, which includes at least 3 weight percent of a pigment; at least 15 weight percent of a hydrolyzed gelatin; and water. The ink composition may also contain conventional additives, such as surfactants and defoaming agents, typically found in flexographic ink compositions. The flexographic ink composition can exhibit better heat resistance, mileage, strength, wet trap, foam resistance, drying, stability, and plate transfer than conventional flexographic inks which contain soy as a binder.
