THERMOPLASTIC RESIN FILM LAMINATE AND RESIN SHEET FOR CARD
Document Type and Number:
WIPO Patent Application WO/2018/074481
Kind Code:
A1
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 be coated with a non-transparent layer and reliably protected. 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 layered on 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.
