<p><P>PROBLEM TO BE SOLVED: To provide a chlorinated polypropylene gravure printing ink having excellent adhesiveness to polyolefin films such as polypropylene and good pigment dispersibility. <P>SOLUTION: The printing ink composition uses an acid-modified chlorinated polyolefin resin as a pigment-dispersing resin. The acid-modified chlorinated polyolefin resin is a chlorinated polypropylene having a molecular weight of 1,000-500,000 and a chlorination degree of 17-40%. In the printing ink composition, the acid component to be used for the acid modification preferably comprises maleic anhydride. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
