Abstract
The present invention relates to a radiation curable composition comprising (a) from 1 to 99% by weight of a (meth)acrylated natural oil which is the reaction product of an unsaturated natural oil with an unsaturated anhydride and a hydroxyl functional (meth)acrylate, and (b) from 1 to 99% by weight of a (meth)acrylated oligomer and/or monomer, and optionally an inert resin and/or filler, as well as their use for making inks and coatings.
Claims15
A (meth)acrylated natural oil which is the reaction product of
- an unsaturated natural oil with an unsaturated anhydride, and
- a hydroxyl functional (meth)acrylate comprising a secondary hydroxyl group,
- wherein the hydroxyl functional (meth)acrylate is a compound of formula (I) or (II)
- R—O—CH2—CH(OH)—CH2—O—CO—CR′═CH7 (formula I)
- R—CO—O—CH2—CH(OH)—CH2—O—CO—CR′═CH7 (formula II),
- wherein R′ is H or —CH3, and
- wherein R=an alkyl or aryl comprising from 4 to 20 carbon atoms, and wherein the (meth)acrylated natural oil is obtained by a process wherein, in a first step, the unsaturated natural oil is reacted with the unsaturated anhydride, followed by a subsequent step wherein the anhydride modified natural oil is reacted with the hydroxyl functional (meth)acrylate.
