Acrylated natural oil compositions

摘要

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.

主权项

1. 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.
