<p><P>PROBLEM TO BE SOLVED: To provide a binder for printing ink which has good close adhesion property to a polyolefin resin and the like without combining chlorinated polyolefin and does not contain toluene. <P>SOLUTION: This binder for printing ink contains a polyurethane resin derived from polyesterdiol (A), an organic diisocyanate compound (B), and if necessary, an amine-type chain extender (C), but does not contain toluene. The polyesterdiol (A) contains polyester polyol (A1) obtained by reacting a polybasic acid component (a1) containing at least an alicyclic dibasic acid (a11) and a polyol component (a2) containing at least an alicyclic diol (a21). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
