Abstract: An aqueous composition comprising i) at least a crosslinkable vinyl oligomer (A) with a weight average molecular weight in the range of from 1000 to 80,000 Daltons obtained by the bulk polymerisation of vinyl monomers ii) at least a vinyl polymer (B) with a weight average molecular weight ?5000 Daltons, obtained by polymerisation in the presence of vinyl oligomer (A) of vinyl monomers where the ratio of vinyl oligomer (A) to vinyl polymer (B) is in the range of from 5:95 to 95:5; where polymer (B) is more hydrophobic than vinyl oligomer (A); and where the weight average molecular weight of vinyl polymer (B) is more than the weight average molecular weight of vinyl oligomer (A).
