Transparent, abrasion resistant coating compositions

Articles coated with transparent, abrasion resistant compositions comprising a colloidal dispersion of a water insoluble dispersant in a water-alcohol solution of the partial condensate of silanol wherein the dispersant comprises metals, alloys and salts thereof.

Articles coated with transparent, abrasion resistant compositions

There is disclosed transparent, abrasion resistant coating compositions comprising a colloidal dispersion of a water insoluble dispersant in a water-alcohol solution of the partial condensate of silanol wherein the dispersant comprises metals, alloys and salts thereof.

A cured transparent, abrasion resistant coating on at least one surface of a substrate. The coating composition comprises an effective abrasion resisting amount of a colloidal dispersion containing colloidal antimony oxide and colloidal silica in a weight ratio of less than or equal to about 30:70, in a water-alcohol solution of the partial condensate of R(Si(OH).sub.3) wherein R is an organic radical.

Coated substrate comprising a cured transparent abrasion resistant

A coating composition which forms an improved transparent, abrasion resistant coating upon curing. The coating composition comprises an effective abrasion resisting amount of a colloidal dispersion containing colloidal antimony oxide and colloidal silica in a weight ratio of less than or equal to about 30:70, in a water-alcohol solution of the partial condensate of R(Si(OH).sub.3) wherein R is an organic radical.
