Claim:
1. A dispersion of polymeric beads, wherein the polymeric beads have an average diameter of between 50 μm and 1500 μm and comprise a copolymer containing styrene in an amount of less than 1.5% by weight of the copolymer, and wherein the copolymer comprises the following comonomers (a), (b), (c) and optionally (d): (a) 24 to 70% by weight of one or more monomers represented by the Formula (1):  where both R (b) at least one acid functional monomer in an amount from 0.5 to 15% by weight sufficient to a achieve an acid value of the resultant copolymer of 3 to 100 mg KOH per gram of copolymer, (c) 0.01 to 10% by weight of one or more monomers represented by the Formula (2):  in which X (d) optionally less than 75% by weight of monomer other than comonomers (a), (b) or (c) and does not contain styrene, butyl acrylate, 2-ethyl hexyl acrylate and/or mixtures thereof; wherein the weight percentages or amounts of comonomers (a), (b), (c) and (d) are calculated as a proportion of the total amount of components (a)+(b)+(c)+(d) which totals 100%; and wherein independently at least one of the comonomers (a), (b), (c) and/or (d) and/or the copolymer obtained from comonomers (a), (b), (c) and optionally (d) are biorenewable which is defined as comprising an amount of carbon-14 sufficient to produce a decay of at least about 1.5 disintegrations per minute per gram carbon (dpm/gC); with the provisos that:
