Patent ID: 8304070

Claim:
A window material, characterized by being a film or a board with a thickness of 0.1 μm to 50 mm, and comprising surface treated zinc oxide particles dispersed in a solid medium, wherein the surface treated zinc oxide particles are obtained through a surface treated zinc oxide particles precursor and further through a dried body according to a manufacturing method comprising: a first step of mixing a dispersion liquid with zinc oxide particles dispersed in a solvent, and a silicone resin having polysiloxane bond with at least one or more silicon atoms having a silanol group (Si—OH) and/or alkoxy silyl group (Si—OR, wherein R is alkyl group); then obtaining a mixed solution containing a surface treated zinc oxide particles precursor, with the silicone resin adsorbed on a surface of the zinc oxide particles and the solvent, and drying and solidifying the mixed solution by removing the solvent from the mixed solution and applying heat treatment thereto, to thereby manufacture a dried body, wherein the silicone resin adsorbed on the surface of the zinc oxide particles has a three-dimensional siloxane bond; and a second step of pulverizing the dried body, to thereby manufacture the surface treated zinc oxide particles.
