A coating agent to be applied and permeated into a print pattern of a water pressure transfer film has a main ingredient of a ultraviolet hardening resin composite containing a photo-polymerization monomer, a photo-polymerization oligomer and a photo-polymerization initiator, said photo-polymerization monomer has 3 or less functional groups and a volume shrinkage coefficient of 20% or less, said photo-polymerization oligomer has 10 or less functional groups, the coating agent further contains polyurethane beads having an average particle diameter of 5 through 50 micrometer and the polyurethane beads are blended at 15 through 100 weight part relative to 100 weight part of said ultraviolet hardening resin composite. This coating agent can impart a softness feeling and a wetness feeling to the surface of the decoration layer by the polyurethane beads.
A water pressure transfer method comprising the steps of applying an ultraviolet hardening resin composite coating agent containing a photo-polymerization ingredient having at least a photo-polymerization monomer and a photo-polymerization initiator on a print pattern of a water pressure transfer film having said print pattern dried on a water-soluble film to recover an adhesion of said print pattern by said activation ingredient of said ultraviolet hardening resin composite and transferring said print pattern on a surface of an article under water pressure to form a decoration layer on the surface of said article and to form an integral layer having said print pattern and said ultraviolet hardening resin composite coating agent intermingled with said ultraviolet hardening resin composite coating agent permeated into the whole print pattern, said decoration layer formed by said integral layer whereby a chemical and physical surface protection function is imparted to said decoration layer itself by said ultraviolet hardening of said decoration layer, characterized in that said photo-polymerization monomer of said ultraviolet hardening resin composite of said coating agent has 3 or less functional groups and a volume shrinkage coefficient of 20% or less, said coating agent contains resin beads having an average particle diameter of 5 through 50 micrometer and said ultraviolet hardening resin composite and said resin beads are blended at 100 weight part versus 15 to 100 weight part.
