    Abstract: Disclosed is a method of self-tanning, pre-tanning and co-tanning skins and hides and for retanning leather and hides, using carbonyl compounds of formula (I), in which R is hydrogen, C1-C8 alkyl groups, phenylalkyl groups with a total of up to 12 C-atoms or phenyl groups, wherein phenyl residues may also be substituted with one or two C1-C4 alkyl groups, C1-C4 alkoxy groups, hydroxyl groups, amino groups, carboxyl groups, sulfo groups or halogen atoms; n is 1, 2, 3, or 4; and x is an OH, SH, NH2 or PH2 residue when n = 1, a bridging O, S, SO, SO2, NH, NR , PH or PR group, where R is C1-C4 alkyl, when n = 2, a tertiary N- or P-atom or the trivalent group P =O when n = 3, and a quaternary N-atom when n = 4. The corresponding acetals or ketals of the carbonyl compounds of formula (I) may also be used.

    Abstract: Novel compounds of the general formula I I where A is a fiber-reactive radical of the triazine, pyrimidine or vinylsulfone series, D is a radical of a sulfo-containing diazo component of the aniline or aminonaphthalene series, K is the radical of a coupling component of the aminohydroxynaphthalene series, X is fluorine, chlorine, bromine, C1-C4-alkyl, trifluoromethyl, C1-C4-alkoxy, phenoxy, hydroxysulfonyl, carboxyl, acetyl, propionyl, methylsulfonyl, ethylsulfonyl, phenylsulfonyl, C1-C4-alkoxycarbonyl, phenoxysulfonyl or unsubstituted or substituted carbamyl or sulfamyl, and Y is fluorine, chlorine, bromine, C1-C4-alkyl, trifluoromethyl, C1-C4-alkoxy, phenoxy, phenoxysulfonyl, acetyl, propionyl, methylsulfonyl, ethylsulfonyl, phenylsulfonyl, p-acetylaminophenylsulfonyl, hydroxysulfonyl, C1-C4-alkoxycarbonyl, hydroxycarbonyl or unsubstituted or substituted carbamyl or sulfamyl, are very useful for dyeing wool and hydroxyl-containing fibers, such as cellulose and in particular cotton.

    Abstract: Use of copolymers obtainable by free-radical copolymerisation of (a) C8-C40-monoolefins with (b) ethylenically unsaturated C4-C8-dicarboxylic anhydrides in the manner of a mass polymerisation at from 80 to 300 DEG C to form copolymers having molecular weights of from 500 to 20,000 g/mol, subsequent solvolysis of the anhydride groups of the copolymers and at least partial neutralisation in an aqueous medium with bases of the carboxyl groups formed in the course of the solvolysis and which are present in the form of aqueous dispersions or solutions, as agents for waterproofing leathers and pelt furs.
