Composition for dyeing keratinic fibres comprising a diamino-N,N-dihydro-pyrazolone derivative, a coupling agent and a polyol

The invention involves a for keratin fibres especially human hair colouring composition for keratin fibres such as, it contained at least a two-amino-n, n-h ketones or their addition salts of alkali oxides, at least one of the couplers and at least one C4-C30 of polyols, and by using this method of composition for dyeing. This invention makes keratin fibers get resistant to light and washing the solid stain.
