Abstract
Abstract A transfer sheet comprising, in laminated combination, a substrate sheet and, provided thereabove, a coloring layer of desired pattern containing a coloring agent possessing heat transferability and a resist layer of a desired pattern containing a metal compound for resist printing and a binder, the metal compound having the capability of causing the coloring layer to lose its heat transferability, either of the coloring layer and the resist layer being nearer than the other to the substrate sheet. Because of the capability of the metal compound, the resist power is very great, whereby ample resist printing effect can be obtained with only an extremely thin resist layer.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
236 words
A dry transfer printing process which comprises: preparing a transfer sheet of laminated construction comprising a substrate sheet, a coloring layer of a desired pattern disposed on one side of the substrate sheet and containing a heat transferable dye as a coloring agent, said dye being selected from the group consisting of disparse dyes, basic dyes, acidic dyes, and oil soluble dyes, and a resist layer of a desired pattern disposed on said one side of the substrate sheet, either above or below the coloring layer, and containing a metal compound for resist printing by chemical action and a binder, wherein the metal compound for resist printing is a compound consisting of one metal selected from chromium, iron, copper, nickel, and cobalt combined with one radical selected from the radicals of hydrochloric acid, nitric acid, acetic acid, formic acid, and oxalic acid, the metal compound for resist printing being capable of causing the coloring agent to lose its heat transferability; superposing the transfer sheet on an article to be transfer-printed in a manner such that the side of the transfer sheet provided with the coloring layer and the resist layer contacts the article thereby to form a superposed structure; and heating the superposed structure so as to selectively heat transfer the coloring agent having heat transferability in parts of the coloring layer which are not laminated with the resist layer to the article to be transfer-printed.
