Abstract

The invention describes novel organosilicon compounds having fluorescent groups, containing units of the formula ##EQU1## 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), PA1 X is identical or different, and is a chlorine atom or a radical of the formula OR.sup.1, where PA1 R.sup.1 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, PA1 E is an organic radical having one or more (meth)acrylate groups, PA1 A is a radical of the formula EQU --R.sup.2 [--NR.sup.3 --L].sub.x or --R.sup.2 [--S--L].sub.x(II), where PA1 R.sup.2 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 ##STR1## x is 1 or 2, R.sup.3 is as defined for R.sup.1 or is a radical of the formula --C(.dbd.O)--R.sup.1, and PA1 L is a fluorescent, organic radical, PA1 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.ltoreq.4, with t…
