Patent ID: 8431646

Claim:
A water-dispersible, -redispersible or -soluble mixture comprising (iii) at least one water-soluble organic polymer and (iv) at least one organosilicon compound having at least a Si—O—Si bond, wherein a content of the organic polymer (iii) is from 40 to 80% by weight based on the sum of organic polymer (iii) and organosilicon compound (iv); the organosilicon compound (iv) comprising an oligomer mixture of alkylalkoxysiloxanes, wherein the oligomer mixture comprises from 50 to 100% by weight of alkylalkoxysiloxanes, wherein the alkylalkoxysiloxanes have a degree of oligomerization of from 2 to 20; wherein the oligomer mixture of alkylalkoxysiloxanes satisfies empirical formula I (R″)Si(OR′″) x O y (I), where groups R″ are identical or different and R″ is a linear, branched or cyclic alkyl group having 1 to 18 C atoms; groups R′″ are identical or different and R′″ is a hydrogen or a linear or branched alkyl group having 1 to 4 C atoms; 1.0<x<2.0; 0.5<y<1.0; and (2y+x)=3.
