摘要：The present invention relates to aqueous isocyanate emulsions and their use asbinders in the production of shaped articles. These emulsions contain
(A) from 80 to 20% by weight, based on the total emulsion, of water;
(B) from 18 to 79% by weight, based on the total emulsion, of an organicpolyisocyanate;< P>
(C) from 0.5 to 15% by weight, based on the total emulsion of a sulfonic acidcorresponding to the formula: ##EQU1## wherein n represents the integers 1 or 2, and
R.sub.1 represents an aromatic hydrocarbon radical containing from 6 to 14 carbonatoms, an aliphatic hydrocarbon radical containing from 10 to 18 carbon atoms, acycloaliphatic hydrocarbon radical containing from 6 to 15 carbon atoms, an araliphatichydrocarbon radical containing from 7 to 15 carbon atoms or an alkaromatichydrocarbon radical containing from 7 to 24 carbon atoms; and
(D) from 0 to 10% by weight, based on the polyisocyanate, of a nonionic, surface-
active agent as an emulsifier.
