<p>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 diamine, a polymeric polyol and an organic diisocyanate, etc. CONSTITUTION:The objective ink contains a main binder consisting of a polyurethane resin produced by reacting (A) a dimer diamine (e.g., a diamine obtained by amidating and reducing a polymerized fatty acid), (B) a polymeric polyol (preferably having a molecular weight of 500-3,000), (C) an organic diisocyanate (e.g., 1,5-naphthylene diisocyanate) and, as necessary, (D) a chain-extender other than the component A (e.g. ethylene diamine) and/or (E) an end termination agent (e.g. di-n-butylamine).</p> |
