发明名称 DOUBLE WAVELENGTH-REFLECTIVE MULTI-LAYER FILM
摘要 PURPOSE: A multilayer film which reflects two visible light wavelength range is provided to ensure excellent visible effect. CONSTITUTION: A double wavelength-reflective multilayer film(2) comprises a reflective layer part(21) in which a resin layer A(23) and a resin layer B(24) are laminated and selectively comprises a protection layer(22). The maximum reflection rate of the multilayer film is 50% or more of 600-700 nm range in case of observing within 15 degrees from the front side. The thickness deviation within 5m of width or length of the multilayer is 1.5um of less.
