Abstract: The present invention relates to an aqueous dispersion comprising dispersed particles of an acrylic copolymer having a volume average particle size diameter (d50) of from 1 to 50 ?m (microns), wherein the aqueous dispersion further comprises (i) an acrylic copolymer dispersant having an alkaline solubility higher than 50 wt. %, and being present in the dispersion in an amount of from 10 to 35% by weight, relative to the total amount of monomers used to prepare the acrylic copolymer of the dispersed polymeric particles; and (ii) decomposition products of an oil-soluble organic initiator.

Abstract: 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 ?m (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 %.

Abstract: There is described a substantially solid, solvent free, radiation curable composition comprising a) optionally from 0.1% to 99.9% by weight of a colorant; and b) from 0.1% to 99.9% of radiation curable polymer obtained and/or obtainable from at least one mono-(terminal functional forming) monomer of formula I: R1(R2)C?CR3(C?O)(X1)nR4 Formula 1, where n is 0 or 1, X1 is oxy or —NR5— (where R5 represents H or optionally substituted organo), R1 independently represents optionally substituted C1-10hydrocarbo, hydroxyl, optionally substituted C2-10hydrocarbo-oxy comprising a ring moiety, and/or carboxy; and R2, R3 and R4 each independently represent H, an optional substituent and/or optionally substituted organo groups and where n is 0, R3 may also represent oxy or —NR5—; and c) optionally from 0.1% to 90% of a radiation curable high molecular weight reactive diluent; and d) optionally from 0.
