Patent ID: 8216670

Claim:
A heat ray shielding glass for vehicle, comprising a glass substrate and a heat ray shielding film formed on at least one surface of the glass substrate, the heat ray shielding film comprising: conductive oxide ultrafine particles dispersed in the film; and a silica binder for binding the ultrafine particles to each other, the silica binder including solid contents produced by hydrolysis and polycondensation of tetraalkoxysilane and trialkoxysilane, wherein a ratio between the solid content made from the tetraalkoxysilane and the solid content made from the trialkoxysilane is within a range of from 60:40 to 80:20 on a weight percentage basis, and a ratio between the conductive oxide ultrafine particles and the silica binder is within a range of from 35:65 to 70:30 on a weight percentage basis.
