Claim:
An organosilicon compound having alkynol groups and comprising units of the formula in which R 2 are identical or different and are a hydrogen atom, a radical —OR 5 , or an optionally substituted hydrocarbon radical, R 3 are identical or different and are a hydrogen atom, a halogen atom, a radical —OR 5 , or a monovalent, optionally substituted hydrocarbon radical, R 4 are identical or different and are a divalent organic radical, X are identical or different and are —O—, —S—, —OC(═O)—, —N(R 6 )— or —N(R 6 )—C(═O)—, R 5 are identical or different and are a hydrogen atom or a monovalent, optionally substituted hydrocarbon radical, R 6 are identical or different and are a hydrogen atom or a monovalent, optionally substituted hydrocarbon radical, e is 0, 1, 2 or 3, f is 0, 1, 2 or 3, g is 0 or a positive integer and h is 0 or a positive integer, with the proviso that the sum e+f is less than or equal to 3 and the organosilicon compound has at least one unit of the formula (III) where e is not zero.
