<P>PROBLEM TO BE SOLVED: To provide an infrared shielding material particulate dispersion liquid, etc., for providing a heat-ray shielding laminated glass which is excellent in visible light transmittance and a heat-ray shielding property, also low in haze value and a few in discoloration due to ultraviolet rays. <P>SOLUTION: The dispersion liquid includes the infrared (heat-ray) shielding material particulate, which is structured of a tungsten oxide particulate or/and a composite tungsten oxide particulate, a plasticizer and a dispersant, wherein the dispersant has a polyglycerol fatty acid ester of HLB value 1-3. In the dispersion liquid, the polyglycerol fatty acid ester is hard to oxidatively deteriorate even if subjected to ultraviolet rays, discoloration of the infrared shielding material particulate does not occur. Therefore, an interlayer of the heat-ray shielding laminated glass is constituted of a resin composition in which the dispersion liquid and a polyvinyl acetal resin etc., are mixed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
