A method for separating and recovering a layered film laminated and adhered with a reactive adhesive, the method including a step 1 of immersing the layered film in an alkaline solution while stirring the layered film with heating at 20° C. to 90° C. or ultrasonically vibrating the layered film and a step 2 of recovering separated single-layered films that constitute the respective layers of the layered film. The reactive adhesive is preferably a reactive adhesive containing a polyisocyanate composition and a polyol composition and more preferably a reactive adhesive containing a polyisocyanate composition, a polyol composition, and a compound having an acidic group.

Separation/recovery method for laminated film

A decorative molded article which is obtained by transferring hydraulically a hydraulic transfer film comprising a transfer layer including at least two layers of a curable resin layer with an active energy ray and a printed design layer such that the curable resin layer with an ionization radiation becomes a surface layer, wherein the printed design layer comprises a layer printed with a design to be raised which is obtained by using an ink containing an inorganic pigment having a degree of swelling of 200% or more, and the surface of the transfer layer has the raised design corresponding to the design of the layer printed with a design to be raised; and a method for producing a decorative molded article having a raised portion, after a hydraulic transfer film is activated and transferred onto a product to be transferred, the hydraulic transfer film includes a support film, and a printed design layer having a curable resin layer and a layer printed with a design to be raised, which is obtained by using an ink containing an inorganic pigment having a degree of swelling of 200% or more, and the printed design layer does not include a solid print layer obtained by using an ink containing an inorganic pigment having a degree of swelling of 200% or more; the curable resin layer is semi-cured; the support film is removed from the transfer layer, the transfer layer is dried, and the curable resin layer is completely cured.

Decorative molded article and method for producing the same

An object of the present invention is to provide a hydraulic transfer film with a transfer layer capable of forming a cured resin layer on a hydraulic transfer body, to provide a hydraulic transfer film capable of forming a clear decorative layer on a curable resin layer, and a hydraulic transfer body having excellent surface properties and a clear pattern. A hydraulic transfer film having a water-soluble substrate film, a hydrophobic transfer layer including a curable resin layer which can be cured by at least one of irradiation with radiation and heating provided on the substrate film, and a peelable film provided on the transfer layer is described along with a method for producing the hydraulic transfer film.
