Abstract: Process for the preparation of I acid urea of the formula in which 7-amino-4-hydroxynaphthalene-2-sulphonic acid (I acid) is subjected to partial reaction with urea in an inert solvent at a temperature from 100 to 140 DEG C and a pressure from atmospheric pressure to 10 bar, unreacted I acid is precipitated in an acidic medium and removed, and, if appropriate, I acid urea is separated from the resulting neutralised solution by adding salt.

Abstract: The invention concerns the use, as markers for hydrocarbons, of leucotriarylmethanes of formula (I) in which Z is an aromatic carbocyclic or heterocyclic group and R , R , R and R are hydrogen, optionally substituted C1-C16 alkyl, optionally substituted phenyl or optionally substituted naphthyl. The invention also concerns hydrocarbons containing such leucotriarylmethanes and a method of detecting leucotriarylmethanes in hydrocarbons.

Abstract: Quinoline compounds of the formula I in which R represents hydrogen, alkyl or alkoxy, R represents alkyl, cycloalkyl or phenylalkyl, R represents hydrogen, alkyl, substituted or unsubstituted phenyl and X represents a radical of the formula in which R and R denote hydrogen, substituted alkyl, cycloalkyl, phenyl, phenylalkyl or denotes a 5- or 6-membered saturated heterocyclic ring R denotes hydrogen, alkyl, alkoxy or halogen and R denotes hydrogen, chlorine, alkyl or R and R denote a bridging member, upon reaction with just phenolic condensation products as electron acceptors produce yellow to orange dyeings which have a higher colour strength and in some cases better light fastness than the dyes produced using compounds of the closest prior art.

Abstract: Photopolymerisable registration materials containing at least one photopolymerisable, olefinically unsaturated organic compound, optionally a polymeric binder, a photopolymerisation initiator, a colour-forming system composed of a colour former and a photooxidising agent, a sensitiser and also, optionally, further additives and/or auxiliaries contain certain 4-phenylpyridines as sensitiser. Said photopolymerisable registration materials are especially suitable for making photoresist layers and lithographic printing plates.
