Radiation curable (meth)acrylated compounds

摘要

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.

1. A radiation curable composition comprising:
a) at least one (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, relative to the total weight of the polyol constituent, at least 30% by weight of one or more dianhydrohexitols, 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), and b) at least one compound (B3) represented by the general formula (VI):
Y—X(A)n′—Y′ wherein:
Y and Y′ independently are the residues of a (meth)acrylating compound;X is the residue of a dianhydrohexitol;A represents a residue of a (poly)caprolactone, a (poly)lactide, a (poly)glycolide, a compound providing epoxide groups, and/or of an alkylene oxide group containing from 2 to 4 carbon atoms; andn′ is an integer from 0 to 10.
