The decorative film includes a metal layer that includes a first area in which an addition concentration of a predetermined element is relatively high, a second area in which the addition concentration is relatively lower than that of the first area, and minute cracks that are formed using the first area as a reference. The casing portion includes a to-be-decorated area to which the decorative film is to be bonded.

A method for manufacturing a lighting button key is provided. The method includes forming a button body by processing a metal plate, attaching a thin film to the button body and performing double etching on a rear surface of the button body to process a symbol pattern. Additionally, the method includes press-forming the rear surface of the button body and an injection material of a transparent or translucent material into the rear surface of the button body to perform injection molding.

A transfer sheet includes, on a base sheet, at least a release layer containing particles and having a surface roughness Ra of 0.15 to 1.0 m, a protective layer containing an ionizing radiation-curable urethane resin and having a Martens hardness of 2.0 to 40.0 N/mm.sup.2, and the adhesive layer containing an acrylic resin, that are laminated in this order. A decorative sheet is formed by transferring the transfer sheet on a support sheet. A decorative article is a resin molded article decorated by using the transfer sheet or the decorative sheet.

A method of manufacturing an emergency lamp switch is provided. The method includes printing a symbol on a film using inks of a plurality of colors and injection-molding an emergency lamp switch body on a symbol print surface of the film. The symbol print surface is transferred to the emergency lamp switch body and the film from the emergency lamp switch body is removed.

A method for injection moulding an optical component (20), e.g. a cover for a luminaire, with an incorporated optical function, the component (20) comprising an injection moulded body (18) and at least one optically functional relief structure (4) applied thereto, the relief structure (4) forming or contributing to the optical function of the component (20) to be moulded, wherein the method comprises: (i) providing an insert (2) comprising the said optical structure (4) in the form of an open-face relief structure (4) provided on a face, surface or portion of the insert (2), (ii) mounting the insert (2) inside a mould cavity (11) in which the component (20) is to be moulded, with the open-face relief structure (4) facing and at least partially abutting a surface portion of the mould cavity (11), and (iii) rear-injection moulding a body (18) of the component (20) within the mould cavity (11) so as to incorporate the insert (2) in the component body (18), wherein the said method is carried out with parameters selected and/or controlled such that during the injection moulding step (iii) the temperature at or on the face, surface or portion of the insert (2) provided with the relief structure (4) remains below the lowest of the glass transition temperature, melting temperature and temperature of onset of thermal decomposition of the material of that face, surface or portion of the insert (2).

A transfer sheet includes, on a base sheet, at least a release layer containing particles and having a surface roughness Ra of 0.15 to 1.0 m, a protective layer containing an ionizing radiation-curable urethane resin and having a Martens hardness of 2.0 to 40.0 N/mm.sup.2, and the adhesive layer containing an acrylic resin, that are laminated in this order. A decorative sheet is formed by transferring the transfer sheet on a support sheet. A decorative article is a resin molded article decorated by using the transfer sheet or the decorative sheet.

A method for manufacturing a decorative molding in which a transfer layer is transferred onto an injection molded product from a transfer sheet simultaneously with performing of injection molding in which at least one knockout pin in a second half-mold is caused to retreat to clamp a first half-mold and the second half-mold together; and the at least one knockout pin is made to advance so that the first half-mold and the second half-mold are released from each other until the second half-mold and the first half-mold open to a predetermined interval, while the transfer layer in a non-transfer area that is to remain on the transfer sheet is pushed against the first half-mold.

A method of manufacturing a case frame is provided. The method includes forming a mold for forming an ultraviolet molding pattern layer, laminating a hard coating layer on a transfer resin film, laminating an ultraviolet molding pattern layer on the hard coating layer, laminating a deposition layer on the ultraviolet molding pattern layer, laminating a printing layer on the deposition layer, and performing transfer IMD on an injection product using a transfer resin film, on which the printing layer, the deposition layer, the ultraviolet molding pattern layer, and the hard coating layer are successively laminated.
