Infrared radiation reflector and infrared radiation transmitting composition

摘要

The infrared reflector of the present invention has an infrared-reflecting layer and an infrared-permeable layer which is formed on the infrared-reflecting layer. The infrared-reflecting layer has a reflectance of 60% or more and a permeability of 25% or less with respect to infrared rays having a wavelength within a range of 800 to 2600 nanometers. The infrared-permeable layer has a reflectance of less than 60%, an absorbance of 50% or less, and a permeability of 30% or more with respect to infrared rays having a wavelength within a range of 800 to 2600 nanometers. The infrared-permeable layer contains resin components and pigments, and the amount of carbon black contained in the infrared-permeable layer is 0.1 wt % or less.
