Abstract:
An aqueous dispersion comprising:i) an organopolysiloxane composed of an organopolysiloxane segment and a poly(N-acylalkyleneimine) segment which is bonded to at least one silicon atom of said organopolysiloxane segment via an alklene group containing heteroatom(s) and which consists of repeating units represented by formula (1): ##STR11## wherein R.sup.1 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; and n is a number of 2 or 3;wherein the weight ratio of the organopolysioloxane segment (a) to the poly(N-acylalkyleneimine) segment (b) is at least 25/75 and less than 40/60, and the weight average molecular weight is from 10,000 to 500,000;ii) water.
