摘要： Provided is an optical film, which, despite including a polarizing plate having a recessed portion or a through-hole, is excellent in handleability, is suppressed from causing the strain of the polarizing plate, and shows a small dimensional change owing to an environmental change. The optical film of the present invention includes a glass film, a polarizing plate, and a pressure-sensitive adhesive layer in the stated order, wherein the polarizing plate has a recessed portion that opens on a surface of the polarizing plate opposite to the glass film, or a through-hole, wherein part of the pressure-sensitive adhesive layer fills the recessed portion or the through-hole, and wherein the glass film has a thickness of from 30 μm to 150 μm.

摘要： A method of conveying a glass film composite uses a roll-to-roll process for winding a glass film composite wound on a feed roller by a winding roller through a plurality of conveyance rollers. The glass film composite includes an elongated glass film, and linear resin tapes disposed on one side of the glass film along a longitudinal direction of the glass film at both ends in a width direction of the glass film. The method includes a step of conveying the glass film composite from the feed roller to the winding roller through the plurality of conveyance rollers without passing a state in which the glass film composite is bent so that the resin tapes are directed to the inside.

摘要： Provided is a method of manufacturing a laminated film, the method including laminating a glass film and a resin film via an adhesive layer, by which peeling between the glass film and the resin film is prevented, and hence a laminated film excellent in appearance can be obtained. The method of manufacturing a laminated film of the present invention includes the steps of: laminating a glass film and a resin film via an adhesive to provide a precursor laminate; and curing the adhesive by applying an active energy ray to the precursor laminate, wherein the curing step includes nonuniformly applying the active energy ray in a surface of the precursor laminate.

摘要： A method of manufacturing a glass resin laminated body includes a step of sticking a glass film on a resin film via an adhesive layer while holding the glass film and the resin film between a first roller that presses against the resin film and a second roller that is disposed opposite to the first roller and that presses against the glass film. A ratio of an elastic modulus P1 of a surface layer of the first roller to an elastic modulus P2 of the resin film P1/P2 satisfies a relation of 3×10−3≤P1/P2≤1.0.
