摘要: A process is disclosed for producing structurally resistant paper (or paper-like materials) with a terminable resistance. Paper pulp is treated in the mass or the surface of finished paper is treated with 0.0001 to 50 % by weight, preferably 0.01 to 25 % by weight (in relation to the paper mass) of a mixture of isocyanates that in average have at least 2 isocyanate groups of which at least 20 % by weight (preferably at least 50 %) have NCO groups bound by an organic residue that contains at least one ester and/or amide group in the main chain.

摘要: The reaction products of polysuccinimides with primary and/or secondary amines and ring-opening bases are remarkably suitable as leather auxiliary products. They give more volume, a soft feel and an extraordinarily smooth and solid grain.

摘要: The present invention relates to means for paper finishing in the form, for example, of aqueous dispersions. They contain: (I) polyisocyanate (PI) with ionic groups and/or ether groups and at least one member of the group consisting of (II) natural polymer (NP) from the polysaccharide group, (III) polysiloxane graft copolymer (SP 1), (IV) water-dilutable synthetic polymer (SP 2) and (V) polymer containing cationic hydroxyl groups (SP 3) or (I) polyisocyanate (PI) as above, (II) natural polymer (NP) as above and at least one member of the group consisting of (III), (IV) and (V), as above.

摘要: The invention relates to a method for producing leather which is both completely biologically degradable and fully wear resistant by means of: I) (pre)tanning using tanning agents containing aldehydes or carbomoyle sulfanate groups, II) optionally (re)tanning with polyasparaginic acids and/or polyasparaginic acid amides, III) bottoming with polyurethane and natural auxiliary agents, finish consisting of polyurethane and/or polyester amide and IV) optionally, after-treatment with leather conservation products.
