Process for the preparation of 3-nitrobenzenesulfonyl chloride

An unsaturated polyester suitable as a binder which comprises a reaction product of

Resin binders and process for preparing them

Benzimidazolone-(2) is obtained in good yield and high purity when o-phenylene diamine is condensed with urea in water at a pH of 4 to 9 and a temperature above 90.degree. C.

Process for the preparation of benzimidazolone-(2)

A composition for use as a binder in a non-aqueous printing ink which comprises a modified hydrocarbon resin containing carboxylic acid units, the carboxylic groups of which are partially esterified with a polyhydric alcohol in such an amount that the modified hydrocarbon resin product contains from 0.01 to 0.7 ester groups of polyhydric alcohol based on each acid group originally present and a process for its preparation.

Modified hydrocarbon resin composition for use in printing ink

A modified hydrocarbon resin comprising (A) a major amount of a cycloaliphatic diene resin component and (B) a minor amount of an olefinically unsaturated polycarboxylic acid component, wherein at least 5% of the carboxyl groups are esterified with an alcohol selected from the group consisting of (a) a monohydric, (b) a dihydric alcohol and (c) a combination of (a) and (b), a process for its preparation and a printing ink composition containing said modified hydrocarbon resin.

Printing ink binder

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.
