Patent ID: 7348393

Claim:
A silane resin that can be structured photochemically and/or thermally, obtained by a one-step condensation of a mixture consisting of: a) at least one silane compound of the general formula (I) R a R 2 b SiX 4-a-b (I) wherein R is a group polymerizable photochemically and/or thermally via an organic group by radical polymerization or cationic polymerization; R 2 is a straight-chain, branched, or cyclic, optionally substituted, C 1 -C 12 alkyl group; X is identical or different and is a leaving group with the proviso that X is not OH; a is 1 or 2; b is 0 or 1, wherein a+b is not more than 2; b) at least one silanediol of the general formula (II) R 1 2 Si(OH) 2 (II) wherein R 1 is identical or different and is a straight-chain, branched, or cyclic, optionally substituted, C 1 -C 12 alkyl group or a group that can be polymerized photochemically and/or thermally via an organic group by radical polymerization or cationic polymerization, with the proviso that the group does not contain an aryl group; and optionally c) at least one component, selected from the group consisting of alkoxides of aluminum, boron and germanium; transition metal alkoxides; lacquer additives; fillers; leveling agents; and pigments; wherein the at least one silane compound of the general formula (I) and the at least one silanediol of the general formula (II) are reacted in a ratio of precisely or approximately 1:1, based on the monomers; wherein condensation is carried out in the absence of water, with the exception of water bonded to a condensation catalyst in the form of a hydrate, in an anhydrous solvent or anhydrous suspension agent and wherein the solvent or the suspension agent and volatile components produced by the condensation are removed subsequently wherein the silane resin is free of SiOH groups.
