  • reaction product of type (II) and its preparation are known from EP-A-0245205.
  • Preferred anionic aromatic syntans are those of groups (I) and (IV), where as (hydroxy) arylsulfonic acid, sulfonated (hydroxy) -naphthalene and sulfonated xylene (as technical mixture), and as diaryl ether sulfonic acid, sulfonated Ditolyl ethers are preferred.
  • component (B) such polymers and copolymers of (meth) acrylic acid, maleic acid, itaconic acid and / or their hydroxy compounds are mentioned which have a molecular weight of 1000 to 30,000, particularly 2000 to 15,000. These polymer compounds can be prepared in a manner known per se (cf., for example, E. Müller, Houben-Weyl, Methods of Organic Chemistry, Volume 14 / I, 1961, 1010-1080 and Volume 14 / II, 1963, 631-633 and 705 -713; Kirk-Othmer (3rd) volume 20, 216-219 and FR-A-2 463 810).

  • the agent according to the invention can be used for pre-tanning leather or for tanning furs.
  • a method for producing wet-white leather and furs thus represents a further subject of the invention.
  • the process for producing wet-white leather and furs is characterized in that after pickling these materials are treated in the presence of a water-soluble chromium, aluminum, iron or zirconium salt or a mixture thereof with an agent according to the invention.
  • the salts that can be used are ready-to-use tanning salts and are described in the relevant specialist literature.
  • Examples of such salts are basic chromium (III) chloride or sulfate, a chrome alum, optionally basic aluminum chloride or sulfate, an alum, iron (III) chloride or sulfate, zirconium oxychloride and zirconium sulfate. Mixtures of the chromium and aluminum salts mentioned can also be used well.
  • the aluminum salts and especially the aluminum sulfate Al2 (SO4) 3 ⁇ 16 H2O.

  • Agents according to the invention which do not contain any of the salts mentioned can also be used as retanning agents with good filling and softening properties.
  • the conventional methods are used to treat pickled pelts or furs (skins) with an aqueous solution which contains the agent according to the invention, and then to wet-white material thus obtained in the usual way with vegetable or synthetic tanning agents or chrome tanning agents is tanned.
  • 100 to 200, preferably 100 to 150 parts by weight of water and 3 to 30 parts by weight of the aqueous composition according to the invention are used per 100 parts by weight of pale or fur.
  • Wet-white materials with a shrinking temperature of 60 to 75 ° C., good light fastness and a light intrinsic color are obtained.
  • agents according to the invention are particularly well suited for the production of wet white leather and furs, their use for this purpose represents a further subject of the invention.
  • the preparation of the agent according to the invention is generally carried out in such a way that an aqueous solution of component (A) is optionally mixed with components (C) and (D) and then with component (B).
  • the aqueous compositions according to the invention preferably contain 64 to 76% by weight of component (A), 18 to 36% by weight of component (B), 0 to 7% by weight of component (C), 0 to 4% by weight of the component (D) and ad 100% by weight water.
  • the agents thus obtained are liquid and have good storage stability. However, they can be dried if necessary.
  • 100 parts of the sulfonation mixture obtained by heating 520 parts of naphthalene and 560 parts of concentrated sulfuric acid at 140 to 160 ° C. for several hours to water solubility, are obtained with 56 parts of a dihydroxydiphenyl sulfone, obtained by heating 540 parts of phenol and 180 parts of 60% for 3 hours. oleum to 170 to 180 ° C and distilling off the excess phenol, and 50 parts of water and 29 parts of formaldehyde (37%) heated at 105 to 110 ° C for 1 hour. The product obtained is then made weakly acidic with ammonia. A water-soluble clear solution is obtained which has a dry content of 51%.
  • 100 parts of the sulfonation mixture obtained by heating 160 parts of xylene mixture and 240 parts of concentrated sulfuric acid at 130 to 135 ° C. for several hours to water solubility, are mixed with 40 parts of a dihydroxydiphenyl sulfone, 32 parts of water and 35 parts of formaldehyde [37%] for 3 hours heated to 100 to 105 ° C.
  • the product obtained is then made weakly acidic with ammonia.
  • a water-soluble clear solution is obtained which has a dry content of 60%.
