Zusammenfassung:	The present invention relates to an aqueous dispersion comprising (i) dispersed particles of vinyl polymer having a volume average particle size diameter (D50) of from 1 to 30 μm (microns); (ii) a partially hydrolysed vinyl acetate (co)polymer in an amount of from 2% to 30% by weight, relative to the total amount of monomers used to prepare the vinyl polymer(s) of the dispersed polymeric particles; and (iii) decomposition products of an oil-soluble organic initiator; wherein at least 95 wt. % of the partially hydrolysed vinyl acetate (co)polymer that is present in the aqueous dispersion has a weight average molecular weight Mw from 25 to 500 kDalton and a hydrolysis degree of from 70 to 95 mol %.
