<p>PURPOSE:To provide the subject binder excellent in adhesivity, boiling resistance and storage stability, and suitable for plastic films, etc., by adding a prescribed amount of a specified imine compound to the solid content of a polyurethane resin. CONSTITUTION:The objective binder comprises (A) 100 pts.wt. of a polyurethane resin obtained by reacting a polymeric polyol such as a polyetherpolyol with a diisocyanate compound such as 4,4'-diphenylmethane diisocyanate and a chain extender such as ethylene diamine and (B) 0.01-50 pts.wt. of a compound having one or more groups of the formula (A is H, methyl) in the molecule, such as ethylene imine. The binder is used for the production of printing ink compositions.</p> |
