Abstract
A description is given of a process for manufacturing materials with a structured coating which can be converted into glass or ceramics, whereby (a) a paint is applied to a substrate obtained from hydrolytic polycondensation of compounds of elements based on glass or ceramics; these compounds (based on monomer compounds) included 25 to 100 molar per cent of at least one silicon compound with a general formula of (I) R'Sir <-3 where R' stands for a hydrolysis- resistance group which can be polymerized thermally and/or by radiation and the R groups, which can be identical or different, which stand for OH groups and/or hydrolysis-sensitive groups, or corresponding quantities of a precondensed compound with a general formula of (I); (B) parts of the applied paint are hardened thermally and/or by radiation, after previous drying if necessary, by exposing only predefined regions of the paint to thermal and/or radiation energy; and (C) the non-hardened regions of paint are removed in a suitab le manner. A description is also given of a paint for use in the above process.
