Abstract:
There is described (pref. non-adhesive) coating compositions (which may be either water or solvent borne) that comprise an autoxidisable vinyl polymer, the autoxidisable polymer having a vinyl polymer backbone 25% to 75% by wt of the autoxidisable polymer; fatty acid residue 25% to 75% by wt of the autoxidisable polymer; Tg from −60° C. to +20° C., Mw from 3500 to 50000 g/mol; and polydispersity from 2 to 10; the autoxidisable polymer obtained by a process of: (A) polymerising ethylenically unsaturated vinyl monomers comprising: at least one epoxy functional vinyl monomer 15% to 100% by wt total monomers in (A); 0 to 85% of at least one other ethylenically unsaturated vinyl monomer, (preferably other than styrenic monomers) by wt total monomers in (A); (B) reacting the epoxy functional polymer from (A) with fatty acids having an average iodine value from 30 to 250 g I2/100 g fatty acid; where composition has: a) a opt. co-solvent content ≦40% by wt of the composition; b) a solids content either ≧30% (aqueous) ≧60% (solvent based) by wt of the composition, the composition as a coating film having a telegraphing value of less than 10 gloss units (difference between an initial smooth gloss minus an initial rough gloss of the film).
