Abstract
Energy curable composition including partially acrylated polyols, and one or more monofunctional or multifunctional free-radically polymerizable ethylenically unsaturated monomer and/or oligomers.
Claims22
An energy-curable composition comprising:
- a) one or more monofunctional or multifunctional free-radically polymerizable ethylenically unsaturated monomer and/or oligomer;
- and
- b) a partially acrylated polyol according to the general expression;
- (Ac)m-R—(OH)n
- where;
- Ac=an acrylate or methacrylate group;
- m+n≥2;
- m≥1;
- n≥1;
- and
- R=any organic residue, wherein the polyol is selected from any of trimethylolpropane, glycerol, pentaerythritol, ditrimethylolpropane, dipentaerythritol and blends thereof and wherein the polyol used in the preparation of the partially acrylated polyol is a poly(alkoxylated) polyol, and
- wherein the energy-curable composition is an ink or coating composition.
