Claim:
A crosslinkable composition comprising (A) at least one crosslinkable compound selected from the group consisting of compounds (A1) of formula A-[(CR 1 2 ) b —SiR a (OR 2 ) 3-a ] x (II) where A is an x-valent polymer radical bonded via nitrogen, phosphorus, oxygen, sulfur, carbon or a carbonyl group, R are identical or different and are monovalent, optionally substituted hydrocarbyl radicals, R 1 are identical or different and are hydrogen or a monovalent, optionally substituted hydrocarbyl radical which may be attached to the carbon atom via nitrogen, phosphorus, oxygen, sulfur or a carbonyl group, R 2 are identical or different and are hydrogen or a monovalent, optionally substituted hydrocarbyl radical, x is an integer from 1 to 10, a is 0, 1 or 2 and b is an integer from 1 to 10 with the proviso that at least two OR 2 groups per molecule are present, and compounds (A2) of the formula R 5 c Z d SiO (4-c-d)/2 (III) where R 5 are identical or different and each is an optionally substituted hydrocarbyl radical which may be interrupted by oxygen atoms, Z are identical or different and are a hydroxyl radical or hydrolyzable radical, c is 0, 1, 2 or 3 and d is 0, 1, 2 or 3 with the proviso that the sum of c+d is less than or equal to 4 and at least two Z radicals are present per molecule; and (B) a calcium carbonate-containing filler (B0) surface-treated with carboxylic acids (C) of the formula R 4 —(OCR 3 2 —C(═O)OH) y (I) where R 3 are identical or different and are hydrogen or a monovalent, optionally substituted hydrocarbyl radical, R 4 is a y-valent, carbon-bonded, optionally substituted hydrocarbyl radical which may be interrupted by oxygen atoms, and y is an integer from 1 to 3.
