A highly crosslinked polysiloxane dye comprising at least 10 Si atoms, including at least one moiety of the formula (I) whose open Si-bonds each are linked to an oxygen atom and open O-bond is linked to a silicon atom in the rest of the polysiloxane, and wherein T is a direct bond or an organic spacer group such as C1-C18alkylene, C2-C12alkenylene, C5-C10cycloalkylene, C5-C10arylene, —C5-C10arylene-(C1-C10alkylene)- each of which may be end-capped towards the linkage to Dye by CO, COO, NR1, CONR1, NR1CONR1, CS, CSS, CSNR1, NR1CSNR1, O, S, SO, SO2, C5-C10cycloalkylene, C5-C10arylene; or T is C3-C18alkylene interrupted, and optionally end-capped towards the linkage to Dye, by CO, COO, NR1, CONR1, NR1CONR1, CS, CSS, CSNR1, NR1CSNR1, O, S, SO, —SO2—, C5-C10cycloalkylene, C5-C10arylene; or is CO; (CH2CH2—O)1-5; COO; N(R1); CON(R1); O; S; SO; SO2; R1 is hydrogen; unsubstituted or substituted, straight-chain or branched, monocyclic or polycyclic, interrupted or uninterrupted C1-C14alkyl; C2-C14alkenyl; C6-C10aryl; C6-C10aryl-C1-C10alkyl; or C5-C10alkyl(C5-C10aryl); and Dye is a residue of an organic dye, is useful for dyeing of organic materials, such as keratin-containing fibers, wool, leather, silk, cellulose or polyamides. |
