<P>PROBLEM TO BE SOLVED: To provide a dispersion liquid of infrared light (heat ray) shielding material fine particles and the like, for providing a heat ray-shielding laminated glass having an excellent infrared light-shielding function, good visible light transmittance and low haze. <P>SOLUTION: The dispersion liquid includes: infrared light-shielding material fine particles composed of tungsten oxide fine particles and/or composite tungsten oxide fine particles; a plasticizer; and a dispersion stabilizer. The dispersion stabilizer contains (I) at least one kind selected from a phosphate compound, a sulfate compound and polyvinylalcohol, (II) an organic acid, and (III) a chelating agent. In the dispersion liquid, dispersibility of the infrared light-shielding material fine particles in the plasticizer functioning as a dispersion medium is improved by the effect of the dispersion stabilizer, and a haze value of a heat ray-shielding laminated glass can be therefore improved by forming an interlayer of the laminated glass from a resin composition prepared by mixing the above dispersion liquid and a polyvinyl acetal resin. <P>COPYRIGHT: (C)2013,JPO&INPIT |
