Abstract:
Provided is a multi-layered weather-resistant multilayer film that exhibits good substrate adhesion, wherein curing problems are avoided, bleed-out is minimized, yellowing is reduced, and weather-resistance is improved. The weather-resistant multilayer film 10 is provided with the following: a transparent film-like substrate C; a UV-absorbing resin layer B laminated on the substrate C and containing a UV absorber; and a first cured resin layer A laminated on the UV-absorbing resin layer B. The first cured resin layer A has a thickness of 1.0 to 10 μm. The UV-absorbing resin layer B has a thickness of 0.5 to 5 μm. The UV-absorbing resin layer B has an absorption wavelength of 200 to 500 nm.
