ANIONIC ISOCYANATE COMPOUND AND ITS USE AS EMULSIFIER

摘要

Provided is a composition comprising (a) one or more polyisocyanate, wherein said polyisocyanate has the structure of formula I: A-NCO  I and (b) one or more compound having the structure of formula II: A-L-Q-G  II wherein A in structure II is identical to A in structure I, L is a linking group formed by a reaction of an isocyanate group with an isocyanate-reactive group, Q is an organic group, and G is an anionic group, and wherein the ratio of the sum of the moles of isocyanate groups plus the moles of said L groups to the moles of said Q groups is 3:1 to 10:1. Also provided is an emulsion in which the particles comprise such a composition and further comprise (c) one or more water-insoluble compound that is different from said polyisocyanate (a).
