Title: Gravure ink for heat lamination
Inventor: YASUZAWA TAKASHI
IPC: C09D11/10
Filed: 1990-12-11
Abstract: PURPOSE:To dispense with adhesives in the lamination of printed films by incorporating three specific polymers in a gravure ink for heat lamination as a binder. CONSTITUTION:An ethylene/vinyl acetate copolymer, a chlorinated polypropylene and a vinyl chloride/isobutyl vinyl ether copolymer are used as a binder. Then, a gravure ink for heat lamination is prepared by mixing the binder, an organic solvent (e.g. toluene), a pigment (e.g. monoazo pigment), a lubricant (e.g. polyethylene wax), an antistatic agent, etc. Using the ink, a biaxially oriented polypropylene film is printed and thermally pressed, thereby permitting its lamination. Accordingly, since no adhesive is needed, no residual solvent remains due to the coating of the adhesive and no aging time for the adhesive is necessary.
