Abstract
Hot melt type traffic paint compositions contain as binders partially ring-hydrogenated resins derived by hydrogenating from 20 to 70% of the aromatic rings of an aromatic hydrocarbon resin obtainable by polymerization in the presence of a Friedel-Crafts catalyst of fractions prepared so as to have a conjugated diolefin content of not more than 1.0 wt % and in a ratio of not more than 3.0% with respect to the total amount of polymerizable ingredients and a total content of indene and its alkyl derivatives of not more than 4.0 wt % and in a ratio of not more than 12.0% with respect to the total amount of polymerizable ingredients, said fractions obtained by distillation of cracked oil fractions which have boiling points in the range from 140.degree. to 220.degree. C. and are prepared by cracking of petroleum. These traffic paint compositions provide a favorable antiweathering property, heat resistance and flow characteristics.
