    Abstract: The present invention addresses the problem of providing a laminate that, in addition to having excellent security properties as a result of adding an information-presenting substance in a stable state, is provided with a resinous transparent layer that can cover a non-transparent layer to reliably protect it. The abovementioned problem is solved by a thermoplastic resin film laminate that comprises at least one transparent layer containing a thermoplastic resin and a non-transparent layer laminated with the transparent layer, in which the transparent layer contains an information-presenting substance that emits fluorescence when irradiated with irradiation light in a specific wavelength range, and in which the transparent layer is layered so as to cover at least part of the surface of the non-transparent layer.

    Abstract: The present invention enables the achievement of: a resin laminate which has high durability, high heat resistance and excellent easy processability, while maintaining transparency; and a card which comprises a resin laminate. The above-described problem is solved by a resin laminate according to the present invention, which is obtained by laminating a plurality of resin sheets, and wherein the outermost resin sheet that constitutes the outermost layer of the resin laminate contains a polycarbonate resin (A) that has a viscosity average molecular weight of from 30,000 to 60,000 (inclusive).

    Abstract: The optical sheet according to the present invention includes a first layer containing a polycarbonate resin and a second layer containing an amorphous polyamide resin, the first layer and the second layer being layered by coextrusion molding. The first layer and the second layer are peelable from each other; and a surface of at least one of the first layer and the second layer has a fine uneven shape formed thereat. Such an optical sheet including a plurality of layers can make the entirety sheet thick at the time of melt extrusion molding, and therefore the layered body during the molding can hold a sufficient amount of heat. This improves the transferability of the fine uneven structure. In addition, the layers may be peeled off so that one of the layers is used. In this case, the optical sheet can be made thinner.
