Abstract: Photocatalyst microparticles are provided in a photocatalyst layer coming into contact with a base film, the photocatalyst microparticles are irradiated with ultraviolet rays, and voids are formed in a boundary region between a protective layer and the photocatalyst layer.

Abstract: A film for in-molding is configured with a transfer film which is transferred to a surface of an injection molding resin, and a carrier film which is not transferred. The transfer film includes a coloring layer which includes ink which is an organic material formed of a thermoplastic resin and applies a design to an in-mold molded product, and inorganic polymer layers formed of a thermosetting resin, and the coloring layer comes into contact with the inorganic polymer layers and is interposed between the inorganic polymer layers.

Abstract: An in-mold molded product of the present invention includes: molded resin; a transfer film sequentially including an adhesive layer in contact with the molded resin, and a coloring layer formed of ink; and a plurality of inorganic filler pieces contained in the coloring layer.

Abstract: An object of the present invention is to provide a process for producing an in-mold decorated molded article, which can eliminate the need for deburring after molding and the need for an extra allowance of the molded article. The process includes: clamping a first mold (1) and a second mold (2) to hold a decorative film (207) between the molds; cutting a transfer layer (302) of the decorative film (207) in the molds; injecting resin (5) into the cavity of the mold; cooling the resin (5); and opening the molds to remove the in-mold decorated molded article on which the transfer layer (302) is disposed.

Abstract: In a grindstone for fabricating a mold which has optical fiber engagement portions of an optical fiber guide block used for aligning optical fibers, two main grinding surfaces are provided to form the optical fiber engagement portions contacted with the sides of the optical fibers and a tip end portion which is contiguous to the two main grinding surfaces and which has a contour contained within a predetermined area. The predetermined area has a triangle shape which is defined by two tangent lines along the two main grinding surfaces and a preselected line drawn between two points determined on the two main grinding surfaces. The two points are decided in accordance with a predetermined formula.
