Intaglio printing ink

The invention discloses an intaglio printing ink which is composed of the following components in parts by weight: 15-20 parts of vinyl chloride-acrylate copolymer resin, 10-15 parts of vinyl chloride-vinyl acetate copolymer resin, 10-15 parts of methyl 2-butenoate modified chloro ether resin, 2-3 parts of kaolin, 2-3 parts of calcium hydroxide, 2-3 parts of barium sulfate, 20-26 parts of ethyl acetate, 10-15 parts of ethanol, 10-15 parts of butanol, 5-6 parts of matting powder, 10-12 parts of titanium white and 0.5-1 part of dispersing agent. The specific composition of the vinyl chloride-acrylate copolymer resin, vinyl chloride-vinyl acetate copolymer resin and methyl 2-butenoate modified chloro ether resin is used as the film forming matter of the ink, and the three resins generate synergistic actions in the film forming process of the ink, thereby effectively improving the heat resistance, adhesiveness and leveling property of the ink.
