摘要:
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

Dyes of the formula ##STR1## where the ring A may be benzofused and R.sup.1 -R.sup.6 have the meaning defined in the specification, with the proviso that at least one quaternizable or quaternary group is present in the molecule; use of said dyes for dyeing or printing polymeric material, and novel amides of J-acid.
摘要:
The sulfonamides have the formula ##STR1## where R.sup.1 is C.sub.1 -C.sub.13 -lkyl, substituted or unsubstituted phenyl, C.sub.1 -C.sub.8 -alkanoyl or substituted or unsubstituted benzoyl, andR.sup.2 and R.sup.3 are each independently of one another substituted or unsubstituted C.sub.1 -C.sub.13 -alkyl, substituted or unsubstituted C.sub.5 -C.sub.7 -cycloalkyl or substituted or unsubstituted piperidinyt, or R.sup.2 may also be hydrogen.
摘要:
J-Acid urea of the formula ##STR1## is prepared by reacting 7-amino-4-hydroxynaphthalene-2-sulfonic acid (J-acid) with urea at from 100.degree. to 140.degree. C. under a pressure ranging from atmospheric pressure to 10 bar in an inert solvent to a partial extent, precipitating unconverted J-acid in an acidic medium and separating it off, and, if desired, isolating J-acid urea from the resulting neutralized solution by salting out.
