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.
