Condensation products of dihydroxyaromatics A, alone or in mixture with mono- or polyhydroxyaromatics C, with diepoxides or polyepoxides B which have been alkylolated by reaction with aldehydes D and whose alkylol groups may have been etherified with alcohols, a process for preparing them, and a method of use thereof in particular as compositions for coating the inside of foodstuff and beverage packaging forms made from metals.

Binders and a method of use thereof as coating material for metal containers

Stoving enamels comprising epoxy resins and carboxyl-functional alkylidenepolyphenols in a quantity such that the carboxyl groups are present at least in equimolar quantities relative to the epoxide groups of the epoxy resins are suitable for coating the inside of metallic food containers and give, on the packaging, baked coating films which are essentially free from migratable constituents carrying epoxide groups.

Epoxy-based stoving enamels comprising carboxyl-functional

Aqueous epoxy resin dispersion comprising (A) an epoxy resin which is a condensation product of (A-1) from 50 to 95% by weight, preferably from 55 to 85% by weight, of one or more epoxide compounds having at least two epoxide groups per molecule and an epoxide equivalent mass of from 100 to 2000 g/mol, (A-2) from 5 to 50% by weight, preferably from 15 to 45% by weight, of an aromatic polyol; and (A-3) from 0 to 25% by weight, preferably from 0 to 10% by weight, of modifying compounds containing at least two epoxide-reactive groups; (B) a dispersant comprising (B-1) a condensation product of a polyol having a weight-average molecular mass (M.sub.w) of from 200 to 20,000 g/mol and an epoxide compound having on average at least two epoxide groups per molecule and an epoxide equivalent mass of from 100 to 10,000 g/mol, and (B-2) if desired other surfactants, preferably nonionic surfactants; (C) a polymer, prepared in this dispersion, of ethylenically unsaturated monomers which are capable of free-radical polymerization or copolymerization; (D) a curing agent for the epoxy resin (A); and (E) if desired, conventional additives and catalysts. These aqueous epoxy resin dispersions are suitable for the production of coatings, in particular for interior coatings of cans for beverages and preserves.

Modified acid polyesters obtained by reaction of polyols with unsaturated polycarboxylic acids or anhydrides thereof and conjugated dienoic acids. These products are suitable as curing agents for epoxy resins, in particular for curing tin can finishes.

Modified acid polyesters and their use as curing agents in heat-curable

A resinous road marking composition comprising in addition to pigments and fillers a hydrocarbon resin having an average molecular weight of up to 10,000 and containing 4 to 50 per cent by weight of chemically built-in phenolic components which composition may contain an additional hydrocarbon resin being free from phenolic components. A process for preparing said composition which is pourable as a hot melt wherein the resinous binder is maintained molten at a temperature in the range from 100.degree. to 200.degree.C and a mixture of the fillers and pigments is added thereto and mixed in homogeneously.
