<p>PROBLEM TO BE SOLVED: To provide an infrared reflection film giving enough heat insulation without re-radiating infrared rays, which solves such a problem that a conventional polyethylene terephthalate (PET) surface protective film itself absorbs external irradiation light and reflected light from an infrared reflection layer to elevate temperature, and thereby, sufficient heat insulation is not obtained.SOLUTION: An infrared reflection film 10 comprises an infrared reflection layer 11, a transparent film 12, and an adhesive layer 13. The infrared reflection layer 11 has two major surfaces; the transparent film 12 is composed of a polymer film essentially comprising a {-(C-CCN)n-} skeleton (polyacrylonitrile skeleton) and supports one major surface of the infrared reflection layer 11; and the adhesive layer 13 is formed on the other major surface of the infrared reflection layer 11.</p> |
