Infrared shielding film forming dispersion liquid and infrared shielding film forming coating liquid, infrared shielding film and infrared shielding optical member, multilayer filter for plasma display panel and plasma display panel

摘要

PPROBLEM TO BE SOLVED: To provide an infrared-shielding film for a multilayer filter for a plasma display panel having low haze while maintaining high visible light transmittance and near-infrared absorbency and a coating liquid for forming the infrared-shielding film and the like used for production of the same. PSOLUTION: The coating liquid for forming the infrared-shielding film includes fine particles of infrared-shielding material composed of fine particles of tungsten oxide represented by general formula, WyOz and/or fine particles of composite tungsten oxide represented by general formula, MxWyOz, a typical metal compound, such as zinc carbonate, and an uncured acrylic self-adhesive resin of hydroxy group type in a solvent. The infrared-shielding film is obtained by performing an aging process of a coating film formed from the coating liquid for forming the infrared-shielding film. PCOPYRIGHT: (C)2010,JPO&INPIT
