The invention relates to compounds with structures of the formulae I to IV ##STR1## in which formulae Tr is a radical of formula V or VI ##STR2## A is --O-- or --NR.sup.1 --, R.sup.1 is hydrogen or a monovalent organic radical,

Branched polyesters

The invention relates to curable mixtures comprising

Curable mixtures containing diethylphenyl biguanide and the use thereof

The invention relates to a substantially anhydrous composition containing

Curable epoxy resin composition

Addition of waxes or wax-like substances, in conjunction with metal salts or metal complexes of organic compounds, to powder coating compositions based on epoxy resins and carboxyl-terminated polyesters affords a matting effect without substantially impairing the other properties of said coating composition.

Powder coating compositions for the preparation of matt coatings

The invention provides a process for producing thin-layered adhesive non-porpous films of lacquer on metal surfaces. An aqueous suspension of a solid thermosetting synthetic resin which contains a special alkylphenyloxethylate and/or a special aminococonut fatty acid oxethylate as wetting agent and optionally extenders is used for the purpose. The synthetic resin is in the form of a fine powder with an average granular size from 0.1 to 10 .mu.m. The film is applied by immersion , spraying, coating, rolling or the like, and the curing is preferably effected at elevated temperatures. The use of mixtures of epoxide resins and phenol-formalehyde resins is preferred.
