of Si-OH groups and prevents premature gelation. Specification 1:23-25.
Independent claims 1 and 10 are illustrative of the invention:
1. A method for producing a lacquer composition, the method
comprising the step of adding silica particles to a reaction mixture
comprising a first organosilane compound and a metal alkoxide under basic
conditions, resulting in a lacquer composition containing silica particles.
10. A starting material composition for obtaining a lacquer
composition, the starting material composition comprising an organosilane
compound, silica particles, a base, and a metal alkoxide.
