The present invention relates to triboelectrically chargeable powder coating materials to which benzimidazole-based additives are added.

Triboelectric chargeable coating powder

Oligomer azo colorants

Oligomeric azo dyes

Cationic sulfonic acid dyes of the formula I ##STR1## where the variables are as defined in the specification, are useful for the dyeing or printing of polymeric material.

Cationic sulfonic acid dyes

Azo dyes and a method of making a hydrocarbon using an azo dye

A process for preparing di- or triarylmethane dyes by oxidation of di- or triarylmethanes in the presence of a diluent and of an oxygen transfer catalyst that contains a complexed heavy metal ion comprises using as oxidizing agent hydrogen peroxide, a hydrogen peroxide donor compound, an organic hydroperoxide or a percarboxylic acid and as the oxygen transfer catalyst a member of the class of the porphyrins, tetraaza�14!annulenes, phthalocyanines or tetraazacyclotetradecanes.

Preparation of DI-OR triarylmethane dyes by oxidation

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.

Basic dyes based on amides of J-acid

Oligomeric triarylmethane dyes

A process for preparing di- or triarylmethane dyes by oxidation of di- or triarylmethanes in the presence of a diluent and of an oxygen transfer catalyst that contains a complexed heavy metal ion comprises using as oxidizing agent hydrogen peroxide, a hydrogen peroxide donor compound, an organic hydroperoxide or a percarboxylic acid and as the oxygen transfer catalyst a member of the class of the porphyrins, tetraaza[14]annulenes, phthalocyanines or tetraazacyclotetradecanes.

Preparation of Di- or triarylmethane dyes by oxidation

There are described dyes of the formula ##STR1## where the ring A may be benzofused, R.sup.1 is substituted or unsubstituted C.sub.1 -C.sub.13 -alkyl, substituted or unsubstituted phenyl, C.sub.1 -C.sub.8 -alkanoyl, substituted or unsubstituted benzoyl, substituted C.sub.2 -C.sub.4 -alkanoyl, or substituted diaminotriazinyl, R.sup.2 is hydrogen or C.sub.1 -C.sub.4 -alkyl or R.sup.1 and R.sup.2 together with the nitrogen atom joining them together are a heterocyclic radical, R.sup.3 and R.sup.4 are each substituted or unsubstituted C.sub.1 -C.sub.13 -alkyl, substituted or unsubstituted C.sub.5 -C.sub.7 -cycloalkyl or substituted or unsubstituted piperidinyl and R.sup.3 may also be hydrogen, R.sup.5 is hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.2 -C.sub.5 -alkanoylamino, halogen, nitro, cyano, substituted or unsubstituted phenylazo, C.sub.2 -C.sub.4 -alkanoylamino substituted by a quaternizable or quaternary group, or C.sub.2 -C.sub.4 -alkoxy, C.sub.2 -C.sub.4 -alkoxycarbonyl or C.sub.2 -C.sub.4 -alkoxycarbamoyl which are each substituted by a quaternizable or quaternary group, and R.sup.6 is hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, halogen, nitro or cyano, with the proviso that at least one quaternizable or quaternary group is present in the molecule, the use thereof for dyeing or printing polymeric material, and novel amides of J-acid.
