    Abstract: Compounds of the general formula I I where E is -CH= or -N=, K is the radical of an amine or of a coupling component of the benzene, naphthalene, pyrazole, pyridine, pyrimidine, quinoline or isoquinoline series, or the radical of a 1,3-dicarbonyl compound which can be coupled, X is -O- or -COO-, Y is -O-, -COO- or -NH-, Z1 and Z2 independently of one another are unsubstituted or substituted alkyl or cycloalkyl, and one of them may furthermore be unsubstituted or substituted aryl, or Z1 and Z2 together with the nitrogen atom are a heterocyclic radical, and Z is unsubstituted or substituted C2- or C3-alkylene, from 1 to 4 sulfonic acid groups can be present and the rings A and B can be further substituted or can carry a fused benzene ring. The compounds of the present invention are suitable for dyeing or printing natural or synthetic N-containing materials, i.e., wool, leather or polyamide or polyurethane fibers, as wells as for coloring inks. The colored salts with amine bases are insoluble in water, but soluble in organic solvent. These colored salts can be used for dyeing organic liquids, resins or surface coatings, wood stains, paste for ball point pens, for coloring anodized aluminum, or for spin-dyeing, i.e., cellulose ester fibers for polyamide fibers.

    Abstract: Reactive dyes which in the form of the free acids correspond to the general formula I where R1 is hydrogen, chlorine, bromine, methyl or hydroxysulfonyl, R2 is chlorine, bromine or phenyl, or is C1-C4-alkoxy which is unsubstituted or substituted by hydroxyl, C1-C4-alkoxy or phenoxy, or is phenoxy or naphthoxy which are unsubstituted or substituted by C1-C10-alkyl and X is fluorine, chlorine or bromine, are exceptionally suitable for dyeing hydroxyl-containing material, e.g. cellulose or leather.

    Abstract: New spirodipyrans of the formula (I) in which A is an optionally substituted benzene or naphthalene nucleus, B is dimethylene, trimethylene or tetramethylene substituted by from 1 to 3 alkyl groups and R1 and R2 are each alkyl of 1 to 6 carbon atoms, which may be substituted by cyano. The compounds (I) give deep blue to violet colorations with acid materials. They may be used for the manufacture of pressure-sensitive recording materials. The compounds (I) exhibit improved solubility in the solvents used for the manufacture of microcapsules.

    Abstract: 1-Aryl-4,5-dihalopyridazones-6 of the formula in which X represents a chlorine or a bromine atom and R represents a phenyl or naphthyl radical which may or may not be substituted are prepared by (1) reacting a mucochloric or mucobromic acid in aqueous mineral acid solution at room temperature with a phenyl or naphthyl hydrazine RNHNH2 and treating the reaction product with concentrated sulphuric acid or by (2) heating a mucochloric or mucobromic acid in aqueous mineral acid solution with a phenyl or naphthyl hydrazine RNHNH2. In the first method the intermediate hydrazone may be isolated and then cyclised by stirring with the sulphuric acid at room temperature. The preferred mineral acid is hydrochloric or sulphuric acid. Unsubstituted pyridazones may be nitrated in the aryl ring and subsequently reduced to the amino compound. The aryl hydrazine may be substituted in the ring by substituents that do not interfere with the mucohalic acid such as methyl, methoxy, carboxy, sulphonic acid, nitro, phenylamino, acetylamino, oxalylamino and benzylamino. Examples describe the preparation by method (1) of the nitrophenyl, 3-amino-6-sulpho-phenyl, acetylamino-phenyl, carboxyphenyl and nitrotolyl - dichloropyridazones with isolation of the intermediate hydrazones and the preparation by method (2) of phenyl, tolyl, sulphonyl and sulphonaphthyl dichloropyridazones and phenyl and tolyl dibromopyridazones.
