<p>PURPOSE:To obtain a water-base printing ink useful for coating a plastic film or plastic sheet. CONSTITUTION:The ink contains a water-based polyurethane resin comprising structural units derived from a carboxylic polymer polyol as the main binder. This film is good in the film-forming properties of the binder, is excellent in pigment dispersion and a printing effect, and is good in adhesion to a plastic film.</p> |
