1. A water pressure transfer method for applying a print pattern onto an article surface including recovering the adhesion of the print pattern dried on a water soluble film of a water pressure transfer film, comprising the steps of:
(a) applying a coating agent for a water pressure transfer film comprising an ultraviolet ray hardening resin composite to be coated on said water pressure transfer film so as to recover an adhesion of a dried print pattern of said water pressure transfer film and so as to permeate the whole print pattern and be integrally combined with said print pattern whereby an ultraviolet ray hardenability is imparted to said print pattern, said ultraviolet ray hardening resin composite containing no organic solvent, but containing at least photo-polymerization pre-polymer, photo-polymerization monomer and photo-polymerization initiator wherein said photo-polymerization pre-polymer is 9 through 40 mass percent of the composite, said photo-polymerization monomer is 50 through 90 mass percent of the composite, said photo-polymerization initiator is of 0.5 through 5 mass percent of the composite, and said ultraviolet ray hardening resin composite has a viscosity of 10 to 100 CPS (25° C.) and a Hildebrand solubility parameter of 10 or more and said photo-polymerization monomer has the viscosity of 3 to 30 CPS (25° C.) and a Hildebrand solubility parameter of 9 or more onto the dried print pattern to recover the adhesion of the print pattern, to permeate the whole print pattern so as to be integrally combined with the print pattern, and to thereby impart an ultraviolet ray hardenability to the print pattern, b) forcibly immersing the article together with the transfer film into water so as to force the surface of the article onto the transfer film whereby the print pattern is transferred under water pressure onto the surface of the article, and c) irradiating an ultraviolet ray on the article to harden the hardening resin compound which is integrally combined with the print pattern whereby an ultraviolet ray hardenability is imparted to the print pattern. |
