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.
