The present invention relates to a process for preparing dye-comprising aqueous polymer dispersions by free-radical aqueous emulsion polymerization of ethylenically unsaturated monomers in the presence of free-radical initiators, in which at least some of the monomers are employed in the form of an oil-in-water emulsion E1 whose disperse phase comprises at least one oil-soluble dye, wherein the disperse phase of E1 is formed essentially of dye-comprising monomer droplets having a diameter <500 nm. The present invention also relates to perylene dyes of the formula III as set forth in claim 35. The present invention relates in addition to dye-comprising formulations which comprise the dye-comprising polymers of the invention and to pigmented formulations which comprise a polymer of the invention comprising optical brightener.

Method for producing aqueous polymer dispersions containing colorants

The invention relates to rylene dyes of the general formula (I), wherein the variables have the following meanings: R represents hydrogen; optionally substituted C -C alkyl-C -C -cycloalkyl, aryl or hetaryl; R&prime; represents optionally substituted C -C alkyl or C -C cycloalkyl, substituted methyl; and n is 0 or 1. The invention also relates to the preparation and use of said dyes for coloring highly molecular organic and inorganic materials and to 9-amino-perylene-3,4-dicarboxylic acid imides (Va) as their intermediate products.

Thermochromic rylene dyes

A process for preparing a supported catalyst comprises the steps of (1) preparation of a copolymer having comonomer units which comprise leaving groups; (2) polymer-analogous reaction with a substituted or unsubstituted cyclopentadienyl compound, and (3) reaction of the copolymer of (2) with a mono-Cp-metallocene compound.
