Composition for oxidative dyeing of keratinous fibres and dyeing process using same

摘要

Composition for oxidation dyeing of keratinic fibers comprises: (a) developer(s); (b) first coupler(s) selected from 1,3-bis(2-hydroxyethylamino)-2-methylbenzene and its acid-addition salts; and (c) second coupler(s) selected from m-phenylenediamine derivatives (I) and their acid-addition salts. Composition for oxidation dyeing of keratinic fibers comprises: (a) developer(s); (b) first coupler(s) selected from 1,3-bis(2-hydroxyethylamino)-2-methylbenzene and its acid-addition salts; and (c) second coupler(s) selected from m-phenylenediamine derivatives (I) and their acid-addition salts. R1 = H, 1-4C alkyl, 1-4C monohydroxyalkyl or 2-4C polyhydroxyalkyl; R2, R3 = H, 1-4C alkyl or 1-4C hydroxyalkoxy; and R4 = 1-4C alkoxy, 1-4C aminoalkoxy, 1-4C monohydroxyalkoxy, 2-4C polyhydroxyalkoxy or 2,4-diaminophenoxyalkoxy, but not methoxy when R1-R3 are all H. Independent claims are also included for: (1) a method for dyeing keratinic fibers comprising applying the oxidation dye composition and developing the color with an oxidizing agent added just before use or applied simultaneously or sequentially in an oxidizing composition; and (2) a kit comprising a compartment containing the oxidation dye composition and a compartment containing an oxidizing composition.
