Abstract

The present invention relates to a compound of formula (I), where A and B are each as defined in claim 1, to its preparation and to its use.

Description

(1) Technical field The present invention relates to dyes for polymer coloring, their preparation and use. (2) Background technology Polymers can be colored in different ways using dyes. One way is dope coloring of polymers, e.g. mixing a pigment or a dye with the polymer and melting the polymer to incorporate the dye into the polymer matrix. Other methods involve coloring (more precisely dyeing) polymers by diffusing dyes from solutions or dispersions into the polymers, examples being dyes made of, for example, polyether, polyacrylonitrile, polyurethane, cellulose or Polymer fibers composed of polyamides are dyed using, for example, disperse dyes, cationic dyes, acid dyes, metal complex dyes or reactive dyes. The use of reactive dyes to form a covalent bond between the dye and the substrate gives these stains / pigments a particularly high fastness. Another method of coloring a polymer is to add a dye to the monomers or oligomers of the polymer before the polymer is formed...
