Abstract
A solar-radiation-shielding material for vehicle windows reduces the visible light transmittance, and reduces the value of solar radiation transmittance/visible light transmittance. The visible light transmittance of the solar-radiation-shielding material is in the range of 5%. The transmission color of the solar-radiation-shielding material satisfies the Expression 2: −14<a*<2, and −8<b*<2.
