PURPOSE:To obtain the subject ink exhibiting excellent adhesivity and printability to PP, etc., even in the form of a one-pack type formulation by using a main binder composed of a polyurethane resin produced by reacting a dimer diol and an organic diisocyanate, etc. CONSTITUTION:The objective ink contains a main binder consisting of a polyurethane resin produced by reacting (A) a dimer diol (e.g. a composition composed mainly of a diol produced by reducing a polymerized fatty acid) and/or (B) a polymerized fatty acid polyester polyol free from amide bond (e.g. a compound produced by reacting a polymerized fatty acid such as oleic acid with a diol, etc.) and optionally (C) a polyol other than the components A and B (e.g. ethylene glycol) with (D) an organic diisocyanate (e.g. 1,5-naphthylene diisocyanate) and, as necessary, (E) a chain-extender and/or (F) an end termination agent. |
