The present invention relates to a radiation curable composition comprising: (I) A radiation curable component comprising a compound having at least one ethylenically unsaturated group and (II) A chlorinated polyester component that is prepared from (A) A polyol component which is substantially free of any Bisphenol A derivative compound and which is substantially free of any cyclic ether polyol compound, said polyol component comprising a polyol compound (Ai) which is cyclic and which has at least two hydroxyl groups, and (B) A polycarboxylic acid component comprising a compound (Bi) having at least one chlorine group and at least two carboxyl groups, (C) optionally at least one monoalcohol compound, (D) optionally at least one monocarboxylic acid compound, (III) optionally at least one polycarboxylic acid compound substantially free of chlorine groups.

Radiation curable compositions

The present invention relates to a (meth)acrylated compound (A) prepared from: (i) a polyol constituent, (ii) a polyacid constituent and (iii) one or more (meth)acrylating compounds, wherein the polyol constituent comprises at least 30% by weight of one or more cyclic ether polyols, relative to the total weight of the polyol constituent, and wherein the compound (A) optionally further contains one or more moieties selected from the group consisting of (poly)caprolactone-containing moieties (ai), (poly)lactide- and/or (poly)glycolide-containing moieties (aii), moieties providing epoxide groups (aiii) and moieties providing alkylene oxide groups containing from 2 to 4 carbon atoms (aiv). The compounds of the invention are in particular suited for the making of radiation curable coating compositions and inks less prone to migration.

Radiation curable (meth)acrylated compounds

The present invention relates to (meth)acrylated compounds (A) prepared from (a) at least one cyclic ether polyol, (b) at least one linking compound (b1) and/or (b2), wherein the linking compound (b1) is selected from cyclic compounds (b11) containing at least one (I) group in the cycle where X=O or NH, from hydroxy acids (b12) and/or from alkylene oxides (b13) containing from 2 to 4 carbon atoms and the linking compound (b2) is selected from epihalohydrins or polyisocyanates, (c) a (meth)acrylating compound; and to their use in radiation curable compositions for the coatings, inks, overprint varnishes, adhesives and composites.
