Abstract

A method of transfer printing, wherein a release layer is formed on a temporary support; printing a pattern on said release layer with an ink containing coloring matter therein to obtain a transfer sheet; superposing an article to be transfer-printed on the printed surface of said transfer sheet; heating the superposed aggregate under pressure to transfer the release layer with the pattern onto said article to be transfer-printed; fixing the coloring matter to said article, and then soaping said article to remove the release layer, characterized in that the release layer consists of (1) 10-90 wt. percent of one or more thermoplastic polymers having excellent film-forming properties and water-solubility or alkaline water solubility as well as organic solvent solubility and (2) 90 to 10 wt. percent of one or more plasticizers having a melting point between 30.degree. and 120.degree. C selected from oxycarboxylic acids or their derivatives having water solubility or alkaline water solubility as well as organic solvent solubility.
