NEAR-INFRARED RAY ABSORBING COMPOSITION CAPABLE OF MAINTAINING EXCELLENT AVERAGE TRANSMITTANCE OF VISIBLE RAY, AND LOW COLOR CHANGE AND TRANSMITTANCE CHANGE OF VISIBLE RAY IN HIGH TEMPERATURE AND HIGH HUMIDITY

摘要

PURPOSE: A near-infrared ray absorbing composition is provided to have excellent transmittance in visible ray region, and barrier property in near infrared ray region, and to have low transmittance change in visible ray region even in case exposed under severe environment of high temperature, high humidity, etc.;CONSTITUTION: A near-infrared ray absorbing composition comprises near-infrared ray absorbing composite oxide particle, and energy-curable resin. The near-infrared ray absorbing composite oxide partice comprises 80-95 weight% of WO3, 1-15 weight% of Cs2O, and a 0.01-5 weight% of Sb2O3 and 0.01-5 weight% of SnO2 particle stabilizer. The near-infrared ray absorbing composite oxide particle has average particle diameter of 1-30 nm, and is comprised in the near-infrared absorbing composition by 5-85 weight%.;COPYRIGHT KIPO 2012
