A coating agent () comprising an ultraviolet ray hardening resin composite () to be applied on a water pressure transfer film () contains no organic solvent, but contains at least photo-polymerization pre-polymer, photo-polymerization monomer and photo-polymerization initiator and having a viscosity of 10 to 100 CPS (25&#xb0; C.) and an ink solubility of 10 or more at an SP value. This can positively and effectively perform the operation of recovering the adhesion of the dried print pattern of the water pressure transfer film and also imparting the ultraviolet ray hardenability to the print pattern.

Coating agent for a water pressure transfer film, a water pressure transfer method and a water pressure transfer article

A decorative layer is formed by applying an ultraviolet ray hardening resin composite on a print pattern of a transfer film and transferring the print pattern on a surface of an article under water pressure in the state where the print pattern is activated by the ultraviolet ray hardening resin composite to recover the adhesion thereof, but the ultraviolet ray hardening resin composite is wholly united with the print pattern and hardened by an ultraviolet ray and the decorative layer has a glossy variation and/or touch feeling in accordance with a combination of the ultraviolet ray hardening resin composite united and hardened with the print pattern and a composition of the print pattern.

Water pressure transfer article

In order to impart, concurrently with the transfer of a decorative layer, a surface protection function able to mechanically and chemically protect the decorative layer to be hydraulic-transferred of an article, a solventless type ultraviolet-curing resin composition is applied onto the dried printed pattern of a transfer film, an article is pushed into water along with the transfer film, with the printed pattern activated by a non-solvent activating component in the ultraviolet (uv)-curing resin composition and its adhesion force reproduced, and a ultraviolet ray is applied to the article to which the printed pattern, now impregnated and completely integrated with the uv-curing resin composition, has been transferred to thereby cure the uv-curing resin composition.

Water pressure transfer method and water pressure transfer article

A pattern-transferring film having a print pattern provided on an upper surface thereof is floated on a liquid surface within a transferring bath and an objective body is immersed into a liquid within the transferring bath together with the pattern transferring film under a liquid pressure so as to transfer the print pattern onto the objective body. The print pattern is obtained by being printed by using an optional printing ink or inks of blue, yellow, red black and white inks or an ink or inks prepared by blending the printing inks. The liquid pressure pattern-transferring ink or inks comprise at least a resin ingredient and a color pigment. The resin ingredient of each of the color inks is composed of a fluoropolymer resin and the color pigment of each of the color inks is an inorganic pigment. In this manner, with liquid pressure pattern-transferring ink comprising the resin ingredient of the fluoropolymer resin and the inorganic pigment in spite of its color, all the color printing inks have a weather resistance of 5000 hours or more determined by a JIS based sunshine weather meter. Thus, there occurs no removal of the transferred pattern out of the objective body which tends to be caused by a deterioration of the resin ingredient, if otherwise and the color of the transferred pattern neither changes nor fades, which enables the article to have its life span maintained for a longer period.

Method of transferring a print pattern composed of a fluoropolymer resin and an inorganic pigment onto an objective body using liquid pressure

A pattern-transferring film having a print pattern provided on an upper surface thereof is floated on a liquid surface within a transferring bath and an objective body is immersed into a liquid within the transferring bath together with the pattern transferring film under a liquid pressure so as to transfer the print pattern onto the objective body. An ink set of at least blue, yellow and red inks is used for printing the pattern on the pattern-transferring film. Each of the printing inks comprises at least a resin ingredient and a pigment including color pigments. The color pigment for the blue ink is a phthalocyanine blue, the color pigment for the yellow ink is an isoindolinone yellow and the color pigment for the red ink is a quinacridone red. The ink set may include one or both of a white ink and a black ink. The color pigment for the white ink is a titanium white and the color pigment for the black ink is a carbon black. All the five color printing inks have a weather resistance of more than 3000 hours on a weather resistance test by a JIS based sunshine weather meter and therefore a color tone of the transferred pattern obtained by using these printing inks is balanced and the pattern transferred article having such a transferred pattern has the same weather resistance, which causes the article to have its life span maintained.

Liquid pressure transfer ink, liquid pressure transfer film, liquid pressure transfer article and liquid pressure transfer method

A transfer film ( ) having a print pattern is floated on a liquid surface ( A) within a transfer bath and a transfer objective body ( ) is immersed into a liquid ( ) within the transfer bath together with the transfer film ( ) whereby the print pattern on the transfer film ( ) is transferred onto the surface of the transfer objective body ( ) using a liquid pressure. The surface portion of the transfer objective body ( ) on which the print pattern should be transferred is immersed under the liquid surface ( A) while the surface portion of the transfer objective body follows the transfer film ( ) so as to be developed thereon in a plane manner by rolling the surface portion of the transfer objective body ( ) on the transfer film ( ). The transfer surface ( ) of the transfer objective body ( ) and the print pattern on the transfer film ( ) are closely attached to each other as if they are adhered in a manner faced to each other with the same area and as a result, the print pattern is closely adhered all over the surface of the transfer objective body ( ).

Hydraulic transfer method and device and hydraulic-transfer article

A pattern transferring film having a print pattern provided on an upper surface thereof is floated on a liquid surface within a transferring bath and an objective body to which a pattern is to be transferred is immersed into a liquid within the transferring bath together with the pattern transferring film under a liquid pressure so as to transfer the print pattern onto the objective body. A liquid pressure pattern-transferring printing ink comprises a resin ingredient having an alkyd resin as a fundamental component, a plasticizer and a pigment. The resin ingredient is composed of a short-oil alkyd resin of 2 to 15 weight % having a cellulose acetate butyrate of 3 to 20 weight % added thereto. The plasticizer for the printing ink is used which has a content of 2 to 4 weight % when the ink is of black and having a content of 0.01 to 2 weight % when the ink is of color other than black. The pattern transferring film is fed onto the liquid surface within the transferring bath so as to transfer the print pattern onto the objective body after the print pattern is treated by an activator to be swelled when being made dry, but as it is when it is in a state of being swelled immediately after printed.
