<p><P>PROBLEM TO BE SOLVED: To provide a polyurethane-urea resin composition for printing ink being soluble in alcohols, having excellent adhesiveness to films, blocking resistance, viscosity stability, etc. by a flexographic printing system and a gravure printing system. <P>SOLUTION: The polyurethane-urea resin composition for alcohol-soluble printing ink is obtained by using an amine compound having≥3 hydroxy groups as a reaction terminator of polyurethane-urea. In the resin composition, hydroxyl value of the polyurethane-urea resin using the amine compound having≥3 hydroxy groups is preferably 0.1-25 mgKOH/g and further, the reaction terminator of the polyurethane-urea resin is preferably 2-amino-2-hydroxymethyl-1, 3-propanediol. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
