Abstract
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° to 200°C and a mixture of the fillers and pigments is added thereto and mixed in homogeneously.
