| 摘要 |
The present invention relates to novel colorants based on monoanthraquinone azamethine derivatives for the mass coloring of polymers, either for polar polymers such as polyamides, polyesters, polycarbonates and ABS; or for non-polar polymers such as polyethylene and polypropylene. <??>The novel colorants are characterized by a substituted or unsubstituted annealed aromatic ring system comprising at least one heteroatom. <??>The novel colorants provide for excellent compatibility with the polymer substrate, excellent heat stability and light fastness.
