Patent ID: 7691920

Claim:
An ink jet ink comprising an ink vehicle, wherein the ink vehicle comprises at least one wax monomer functionalized with at least one cationically curable reactive group and at least one radically curable reactive group, the cationically curable reactive group is selected from the group consisting of epoxide groups and oxetane groups, and the at least one wax monomer comprises a hydrocarbon having a chain length of at least 9 to about 70 carbon atoms, wherein the wax monomer is selected from the group consisting of where X=OH, NH 2 , NCO, CO 2 H or CO 2 R in which R is an alkyl group; Y(CH 2 ) b Y, where Y=OH, NH 2 , CO 2 H, and b is greater than 9; Z(CH 2 ) b Z, where Z=CO 2 R, COCl, b is greater than 9, and R represents an alkyl group; where m+n is greater than 10; where m+n is greater than 10; where m+n is greater than 10, and Z=OH, OR, Cl, OCOR, in which R represents an alkyl group; CH 3 (CH 2 ) a OH, where a is 25 to 50; CH 3 (CH 2 ) a CO 2 H, where a is 26 to 50; and CH 3 (CH 2 ) b CO 2 H, where b is 9 to 24.
