Abstract
Aqueous dispersions (L) comprising:(a) a wax which is(a1) a carboxyl-containing hydrocarbon wax or a mixture of such waxes or a mixture of (a1) and(a2) at least one unmodified hydrocarbon wax,(b) a (co)poly(meth)acrylamide or (co)poly-(meth)acrylamide mixture which is(b1) at least one macro(co)poly-(meth)acrylamide, which optionally contains carboxyl-containing comonomers, having an average molecular weight {overscore (M)}W=n·106, where n≧10,or a mixture of (b1) and(b2) at least one (co)poly(meth)-acrylamide, which optionally contains carboxyl-containing comonomers, having an average molecular weight {overscore (M)}W<10·106,and (d) a dispersant system consisting of amphoteric, anionic and/or nonionic surfactants, are surprisingly useful as highly effective crease mark inhibitors having an extremely surfacy effect and are also suitable for particularly short liquors, for example in winch becks and jet-dyeing machines.
