Organosilicon compounds having fluorescent groups, their preparation and use

摘要

The invention describes novel organosilicon compounds having fluorescent groups, containing units of the formula where R is an identical or different, a monovalent, optionally substituted hydrocarbon radical having from 1 to 18 carbon atom(s) per radical, which may be interrupted by one or more oxygen atom(s), X is identical or different, and is a chlorine atom or a radical of the formula OR1, where R1 is a hydrogen atom, or an alkyl radical having from 1 to 8 carbon atom(s) per radical which may be substituted by an ether oxygen atom, E is an organic radical having one or more (meth)acrylate groups, A is a radical of the formula -R2[-NR3-L]x or -R2[-S-L]x(II),where R2 is a divalent or trivalent, optionally substituted hydrocarbon radical having from 2 to 50 carbon atoms per radical, which is substituted by one or more groups of the formulae x is 1 or 2, R3 is as defined for R1 or is a radical of the formula -C(=O)-R1, and L is a fluorescent, organic radical, a is 0, 1 or 2, b is 0, 1, 2 or 3, c is 0, 1, 2 or 3, d is 0, 1 or 2 and the sum a+b+c+d
