<p>PURPOSE:To provide the titled compsn. which exhibits excellent adhesion to plastic molding and has improved re-solubility, by reacting a chain lengthening component consisting of a specified polyol component, a diisocyanate compd. and a specified diamine mixture. CONSTITUTION:The titled compsn. contains, as a vehicle component, a polyurethane resin obdd. by reacting a chain lengthening component consisting of a polyol component (A) contg. at least 50wt% polyether, an aliph. or alicyclic diisocyanate compd. (B) having an isocyanate group attached to a carbon atom having two hydrogen atoms and a mixture (C) of hydrogenated xylylenediamine and hydrogenated 4,4'-diphenylmethanediamine (2:8-4:6 by weight). A printing ink using this compsn. exhibits excellent adhesion to any of polyolefin, polyester and polyamide moldings. The ink exhibits excellent printability, such as re-solubility in case of piling or mottling and clear printing can be achieved.</p> |
