Hybrid dye intermediate based on indole / indoline hybrid and dye based on indole / indoline

摘要

The present invention, structure (I): (wherein represents a group derived from indoline derivative or indole as a melanin precursor, is Y, X is the oxidation of the developer type or color former X-S-Y represents a group derived from an indoline derivative or an indole as a melanin precursor or dye-based intermediate component is a common element of the Y groups and X, S represents a group of the spacer at least one direct bond or . regarding hybrid dye intermediates based on indoline and indole and hybrid dye-based and has a), the indoline and indole. The products of the present invention, keratin fibers are particularly suitable for dyeing hair, particularly human. By using a dye having a dye, a series of problems that arise when using complex dye mixtures is significantly reduced, or avoided.
