Patent ID: 8114950

Claim:
A β-ketocarbonyl-functional organosilicon wax comprising at least one Si-bonded radical B of the formula [R 3 CH 2 —C(═O)—CHR 3 —C(═O)—X-] y L-(Si) (I), where R 3 is a monovalent, optionally substituted hydrocarbon radical having at least 12 carbon atoms, X is a radical of the formula —O—, —NH—, —NR 2 — or —S—, where R 2 is a monovalent hydrocarbon radical having 1 to 18 carbon atoms, which may comprise one or more separate nitrogen atoms, L is a (y+1)-functional organic radical, y is 1, 2 or 3, and (Si)— is the bond to an Si atom, with the proviso that R 3 is present in an amount of at most 30% by weight, based on the total weight of the organosilicon wax.
