POLYMERIC DYES

摘要

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.
