  • Patent number: 10350910
    Abstract: The present invention addresses at least the problem of providing a method for forming a high-resolution foil image regardless of the hydrophilicity of a recording medium. In order to solve said problem, the present invention provides a method wherein an adhesive ink that is formed by dispersing or dissolving a polymer resin in water and in a water-soluble organic solvent is used as an adhesive for a foil, the adhesive is applied by means of inkjet printing, and a foil image is formed. The polymer resin of the adhesive ink is a polymer of a monomer that includes (meth)acrylic acid and a (meth)acrylic acid alkyl ester having a C2-12 alkyl group, the acid value of the polymer resin being 50-120 mg KOH/g, and the glass transition temperature of the polymer resin being 30-110° C.
