<p><P>PROBLEM TO BE SOLVED: To provide: a low boiling-point solvent soluble resin which is excellent in heat resistance and can be used as a printing ink composition; an ink material using the resin; and ink. <P>SOLUTION: A polyamide-imide resin is composed of trimellitic acid chloride and bis[4-(3-aminophenoxy)phenyl]sulfone. For example, the polyamido-imido resin is melted in such an organic solvent as 1-methyl-2-pyrrolidone, dihydorofuran-2(3H)-on, cyclopentanone, bis(2-methoxyethyl)ether, and 1, 2-bis(2-methoxyethoxy)ethane, can be used as a white ink material since it has high transparency, and can be used for a heat-resistant ink of any color by being added with each color pigment or a colorant. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
