Abstract
Phosphines and/or diphosphines of the formula <IMAGE> in which R<1> and R<2> are identical or different and are C2- to C14-alkyl, C4- to C14-cycloalkyl or C6- to C10-aryl radicals, and X is identical to R<1> or R<2> or is the <IMAGE> group where R<1> and R<2> are as defined above, are used as hydrolysis-stable agents for preventing discoloration of the core in the production of isocyanate-based foams.
