    摘要： A method for treating leather with a low fogging, substantive, retan fatliquor containing a solution or a dispersion of a selected amphiphilic copolymer, substantially free from organic solvents, formed from a predominant amount of at least one hydrophobic monomer and a minor amount of at least one copolymerizable hydrophilic monomer. The method produces leather having desirable strength and softness qualities and particularly reduced fogging characteristics. The treated leather is particularly suitable for use in vehicle upholstery.

    摘要： Disclosed is a method for producing leather, which is characterized in that pelts, pickled pelts, or semifinished products are treated with at least one polymer that can be obtained by copolymerizing (A) at least one ethylenically unsaturated monocarboxylic acid or dicarboxylic acid comprising 3 to 8 C atoms or at least one anhydride derived from a monocarboxylic acid or dicarboxylic acid comprising 3 to 8 C atoms, (B) at least one vinyl aromatic compound, (C) at least one alkoxylated unsaturated ether of general formula (I), (D) optionally, additional monoethylenically unsaturated monomers. The variables in formula (I) are defined as follows: R1, R2, R3 are identical or different and are selected among C1-C4 alkyl or hydrogen; R4, R5 are identical or different and are selected among C1-C4 alkyl or hydrogen; R6 is selected among hydrogen, SO3M, PO3M2, C1-C30 alkyl, -CO-H (formyl), CO-C1-C20 alkyl, -CO-C6-C14 aryl; M represents alkali metal, NH4+, or CH3; n represents an integer between 3 and 100; and y represents an integer between 0 and 10.

    摘要： The invention relates to a method for producing leather. Said method is characterised in that pelts, pickled pelts or semi-finished products are treated with at least one polymer obtained as follows: copolymerisation of at least one ethylenically unsaturated dicarboxylic acid anhydride (A), derived from at least one dicarboxylic acid with 4 to 8 C-atoms, at least one vinyl aromatic compound (B) and optionally one ethylenically unsaturated monomer (C), which comprises at least one heteroatom and differs from (A); reaction with at least one compound (D) of general formula I a or I b, whereby at least 0.55 of an equivalent (D) is used in relation to (A); and optional hydrolysis using water or an aqueous alkaline solution. In formulas I a and I b the variables are defined as follows: A1 can be identical or different and can represent C2-C6 alkene, R1 represents linear or branched C1-C20 alkyl, n represents a whole number between 6 and 200.
