Abstract

Colored organopolysiloxanes comprising units of the formula R 1 a (RO) b A c R 2 d SiO (4−a−b−c−d)/2   (I), in which R is hydrogen or a monovalent, unsubstituted or substituted hydrocarbon radical, wherein R is identical or different among the units of the formula (I); R 1 is hydrogen or a monovalent, SiC-bonded, unsubstituted or substituted hydrocarbon radical, wherein R 1 is identical or different among the units of the formula (I); R 2 is a substituted monovalent hydrocarbon radical, wherein R 2 is identical or different among the units of the formula (I); A is a hydrophilic organic dye radical or its complex compound with a metal, which contains at least one triazine ring via which it is bonded to the unit of the formula (I), wherein A is identical or different among the units of the formula (I); a is 0, 1, 2 or 3; h is 0, 1, 2 or 3; d is 0,1, 2 or 3; and c is 0, 1 or 2; wherein a+b+c+d≦3; wherein d is 0 in the units of the formula (I) where c is not 0; and wherein the organopolysiloxane has at least one radical A per molecule.

Claims (37)

1 - 7 . (canceled)

8 . A colored organopolysiloxane comprising units of the formula

in which

R is hydrogen or a monovalent, unsubstituted or substituted hydrocarbon radical, wherein R is identical or different among the units of the formula (I);

R 1 is hydrogen or a monovalent, SiC-bonded, unsubstituted or substituted hydrocarbon radical, wherein R 1 is identical or different among the units of the formula (I);

R 2 is a substituted monovalent hydrocarbon radical, wherein R 2 is identical or different among the units of the formula (I);

A is a hydrophilic organic dye radical or its complex compound with a metal, which contains at least one triazine ring via which it is bonded to the unit of the formula (I), wherein A is identical or different among the units of the formula (I);

a is 0, 1, 2 or 3;

b is 0, 1, 2 or 3;

d is 0, 1, 2 or 3; and
