Solar heat-ray shielding paint made up of ultrafine ceramic particles is capable of shielding solar heat-rays through reflection and absorption while maintaining high visible light transmittance. It is effective in curbing temperature increases indoors and in cars, particularly in the summer, while maintaining the feeling of openness and also without reducing incoming daylight from windows. It makes it possible to save energy and reduce CO₂, diminishing the air-conditioning load. It can be applied to a wide variety of substances such as glass as well as film and other plastic products.
