Method for optically lightening, dyeing or printing fibrous materials, and in particular textile goods, characterized in that the fibrous material is treated in the presence of alkaline-acting agents and, if necessary, at elevated temperature, with optical brighteners or with dyes having one or more reactive hydrogen atoms (linked, preferably, by means of nitrogen, oxygen or sulfur) or which are capable of forming one or more such hydrogen atoms during the process, but lacking reactive substituents with the fibers and with polychromatic achromatic compounds of the formula ** (See formula) ** where Y means an aliphatic bridge member containing a carbon chain of which one carbon atom is bonded to B and another to R1, B means an acidifying substituent, R2 means an alkenyl or halogenalkyl group of low molecular weight, linked by means of a bridge -SO2O or -CO-, R1 means a non-aromatic hydrazinic radical having a quaternary nitrogen atom directly linked to Y in which the quaternary nitrogen atom is bound with its substituents by simple bonds; having, in the cyclic compounds, saturated character the ring presenting the quaternary nitrogen atom; n is 1, 2, or 3, m means the valence of the anion, and anion ⊖ means the negative radical of a monobasic or polybasic acid.
