Title:
THERMOPLASTIC RESIN MULTILAYER FILM, METHOD FOR MANUFACTURING SAME, AND LAMINATE
Document Type and Number:
WIPO Patent Application WO/2018/199161
Kind Code:
A1
Abstract:
Provided are a thermoplastic resin multilayer film and a method for manufacturing the same in which exceptional light resistance is achieved and roll staining during production and bleed-out are suppressed. This thermoplastic resin multilayer film comprises two outermost surface layers (11 and 13) that are configured from a thermoplastic resin (R1) containing acrylic multilayer-structure polymer particles (A), and an intermediate layer (12) that is configured from a thermplastic resin (R2) containing the acrylic multilayer-structure polymer particles (A) and is laminated between the two outermost surface layers, wherein the thermoplastic resin (R1) contains an ultraviolet absorber in an amount of 2.0-4.0 parts by mass per 100 parts by mass of the thermoplastic resin, the thermoplastic resin (R2) contains an antioxidant and/or a light stabilizer, the total of the antioxidant content and the light stabilizer content is at least 0.2 parts by mass per 100 parts by mass of the thermoplastic resin (R2), and at least one of the outermost surface layers (11 and 13) has a surface roughness Ra of 0.025 µm or less.
