发明名称 |
Dye composition for the direct dyeing of keratinic fibres, containing at least one N-substituted cosolubilized 2-nitroparaphenylenediamine and corresponding processes for dyeing keratinic fibres |
摘要 |
The invention provides a composition and process for directly dyeing keratinic fibres. The combination of 1-N-methylamino-2-nitro-4-N'-methyl-N'-(2' ,3'-dihydroxypropyl)amino benzene with certain 2-nitroparaphenylenediamine direct nitro dyes produces a dye composition in which the dyes can be more concentrated (without crystallizing out) and hence produce darker shades.
