Abstract: The present invention relates to polyisocyanate compositions containing reversibly blocked catalysts for the isocyanate addition reaction, characterized in that they contain (a) at least one organic polyisocyanate, (b) at least one addition product dissolved or dispersed in the polyisocyanate compositions, of a sulfonyl isocyanate with a tertiary amine and/or with a catalyst having a tin(II)- or tin(IV)-carboxylate structure as the reversibly blocked catalyst. The present invention also relates to a process for producing these polyisocyanate compositions and to the use of new polyisocyanate compositions as reactants for compounds containing isocyanate-reactive groups for the production of isocyanate addition products such as polyurethane plastics using a one-component or two-component principle. The present invention finally relates to the latent polyurethane catalysts prepared from a sulfonyl isocyanate and a tin(II)- or tin(IV)-carboxylate.
