A coated glass product includes a glass substrate and a porous antireflection surface coating including SiO-based particles having a first particle fraction including a first characteristic particle size range and a second particle fraction having a second characteristic particle size range that is different from the first characteristic particle size range. In addition, a method for producing the coated glass product is provided.

[object Object]

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&#x3c;y&#x3c;4 and 0&#x3c;x&#x3c;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&#xb0; C. for several minutes, and thermally tempered by a flow of air.
