Abstract
The invention relates to thermally tempered safety glass comprising an non-abrasive and porous SiOlayer which is stable during sintering and has a refractive index of between 1.25 and 1.40. The inventive safety glass can be obtained by coating standard soda-lime glass with an aqueous coating solution having a pH value of between 3 and 8 and containing between 0.5 and 5.0 wt. % of [SiO(OH)]particles (0<y<4 and 0<x<2) having a particle size of between 10 and 60 nm, and a surfactant mixture. The coated glass is then dried, thermally hardened at temperatures of at least 600° C. for several minutes, and thermally tempered by a flow of air.
