    Abstract: Oxalic acid derivatives of the formula in which R and R denote hydrogen, C1-C4-alkyl or phenyl, X denotes hydroxyl, nitro or a radical of the formula -NR R , in which R represents hydrogen or C1-C4-alkanoyl and R represents hydrogen, C1-C4-alkyl or phenyl, Z denotes C2-C8-alkylene, optionally substituted phenylene, optionally substituted naphthylene or X-Z and R , together with the nitrogen atom linking them, denote the radical of the formula in which R has the abovementioned meaning, L denotes a bridge member and Y denotes vinyl or a radical of the formula -C2H4-A, in which A represents hydroxyl or a group which can be removed under alkaline reaction conditions, and their use as intermediates for the production of dyestuffs.

    Abstract: 2-hydroxyphenyl ureas of formula Q-N(R )-CO-NR R (I) are new. Q = a gp. of formula (II); X = NO2 or NH2; X = NO2, NH2, SO3H, sulphamoyl, 1-4C mono- or dialkylsulphamoyl or -S(O)n-Y; n = 0 or 2; Y = vinyl or C2H4-Q; Q = OH or a gp. eliminated under alkaline conditions; R = H, opt. substd. 1-6C alkyl, opt. substd. with 1 or 2 ether O, imino or 1-4C alkylimino gps. in the chain, or 3-4C alkenyl; R , R = opt. substd. 1-6C alkyl, opt. with 1 or 2 ether O, imino or 1-4C alkylimino gps. in the chain, or opt. substd. phenyl; or R = H or L-N(R )-CO-N(R )-Q; L = 2-8 C alkylene or phenylene; or R +R = (-C2H4)2N-R .

    Abstract: Reactive dyes of the formula where n is 1 or 2, X is a six-membered halogen-containing nitrogen heterocycle, L1, depending on n, is fluorine, chlorine, C1-C4-alkoxy, phenoxy, C1-C4-alkyl, substituted or unsubstituted phenyl or a bridge member which has one or two hydroxysulfonyl groups, D is the radical of a diazo component of the aniline or naphthalene series which has at least one hydroxysulfonyl group, L2 is hydrogen or substituted or unsubstituted C1-C8-alkyl, L3 is the cationic radical of an aromatic heterocycle which is linked to the pyridone ring via a nitrogen atom, and L4 is hydrogen or C1-C4-alkyl, with the proviso that the number of hydroxysulfonyl groups in the molecule exceeds that of the cationic groups by at least one, are useful for dyeing and printing hydroxyl- or nitrogen-containing substrates.
