Abstract

The invention comprises dyes of formula R-CO-O-CO-R1, wherein R is an organic grouping containing a chromophore and R1 is an alkyl group which optionally bears halogen acyl or acylamino substituents. The dyes may be used to colour polyamide materials, e.g. wool or nylon by immersion in a hot aqueous dispersion of the above dyes containing acetic acid followed by treatment with sodium carbonate. The dyes are presumed to react with the fibre. Specified values of R are monoazo and anthraquinone dyes. In examples 1-(21-methoxy-phenylazo)-2-hydroxy -3-naphthoic acid, 1-(41-carboxyphenylazo)-2-naphthol, or 4-carboxy-41-dimethylamino-azobenzene is dissolved in methylene chloride with the addition of trimethylamine and ethyl chloriformate is added. The dyes containing the group -CO-O-CO-C2H5 are obtained from the mixture by distilling off the methylene chloride in vacuo, dissolving the residue in dioxan, pouring the solution into water and filtering off the dye.
