INFRARED-REFLECTING FILM

摘要

An infrared-reflecting film has a reflective layer and a protective layer layered in order on one surface of a substrate, and exhibits excellent solvent resistance. The protective layer contains polymers including polyacrylonitrile (PAN) and polymethacrylonitrile (PMAN), and has a gel content ratio of 65% or more after each of the following dissolution tests are performed: a dissolution test with methyl ethyl ketone, a dissolution test with dimethyl formamide, and a dissolution test with methylene chloride.
