  • Patent number: 5102497
    Abstract: A transfer member with a pattern of metallic luster is so constructed that a release layer is formed on the whole surface of a release sheet, a metal thin film layer is formed on the release layer, and a pattern-like adhesive layer including thermosetting resin and 5-70 parts by weight of loading pigment is formed thereon. As required, the metal thin film layer is partially formed to partially form a color adhesive layer on the release layer. The metal thin film layer is formed on the whole surface of the release layer formed on the whole surface of the release sheet, then, the pattern-like adhesive layer is formed on the metal thin film layer, thereafter a part of the metal thin film layer which is not covered with the adhesive layer is dissolved and removed therefrom by alkaline or acidic aqueous solution, and then the pattern-like color adhesive layer is formed thereon to manufacture a transfer member.

  • Patent number: 4292103
    Abstract: A method of transfer printing wherein an adsorptive porous layer of activated alumina or silica or a mixture thereof is formed on the surface of an object to be colored or printed, and a transfer material comprising a carrier sheet and a design layer formed thereon and containing colorants forming a colored pattern is applied to the adsorptive porous layer of the object, and the carrier sheet is stripped away so that the design layer is left adhered to the adsorptive porous layer, and then heat is applied to cause the colorants in the design layer to migrate into the porous layer for exact reproduction of the colored pattern thereon.
