Abstract: A solvent-type gravure ink for a laminate according to the present invention contains a pigment, a binder resin, an organic solvent, and water. The solvent-type gravure ink contains 80 to 100 mass % in total of a polyurethane resin and a vinyl chloride copolymer resin in 100 mass % of the binder resin, and the mass ratio of polyurethane resin to vinyl chloride copolymer resin is 95:5 to 40:60. The solvent-type gravure ink contains 1 to 50 mass % of a structural unit derived from a polyether in 100 mass % of the polyurethane resin. The solvent-type gravure ink contains 0.1 to 15 mass % of a glycol ether-based organic solvent serving as the organic solvent and 0.1 to 5 mass % of the water in 100 mass % of the gravure ink.

Abstract: A method of recovering and recycling solvents, comprising, during printing or coating of solvent-recoverable and recyclable printing ink composition comprising solvents, a step of recovering the solvents vaporized in a solvent recovery apparatus, a step of separating the solvents obtained into one or more single solvents and/or one or more azeotropic compositions of two or more solvents by multi-stage distillation, and a step of recycling them as a printing ink raw material and/or dilution solvent raw material.
