    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.
