Abstract: A color image transfer method includes performing solid printing of an image portion on a hydrophilic transfer sheet coated with a water-soluble resin with an aqueous solution ink containing a component that dissolves the resin and imparts the resin with an adhesive property for a desired time by use of an ink jet printer, scattering heat-bondable resin powder onto the solid printed portion and fixing it thereto while removing the powder from portions other than the image portion, printing with a sublimation ink so that the image may be in register with the solid-printed image, superimposing the image surface on an article to be transferred and heat pressing, and peeling off the transfer sheet from the article to be transferred by giving moisture to the transfer sheet. The method enables single-part production of articles for full color image printing and can transfer only an image portion as in screen printing.
