Abstract: 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.

Abstract: 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.
