Abstract
Cyclic carbamate functional compounds, which are the reaction product of a cyclic carbamate having an acrylate functional group, such as N-(2-acryloyloxyethyl)oxazolidinone, with aliphatic amine compounds, said cyclic carbamate functional compounds being useful as oxygen scavengers in energy-curable compositions, such as inks, coatings and adhesives, that comprise (a) the cyclic carbamate functional compound, (b) reactive monomers and/or oligomers and, optionally, (c) a photoinitiator.
Claims15
A cyclic carbamate compound comprising a compound of the formula (I):
- wherein:
- R1 is a moiety of the formula (II):
- in which m is 1, 2 or 3;
- n is from 1 to 8;
- o is from 1 to 10;
- and
- each R is independently selected from H and methyl;
- R2 is an aliphatic chain, optionally linked to a moiety of the formula (III):
- either R3 is selected from:
- an aliphatic group, optionally linked to a further moiety of the formula (III),
- a further moiety of the formula (II), or
- a unit containing an acrylate or other functional group that is curable in a free radical curing reaction;
- or R3 and R4 together form an aliphatic chain;
- and
- R4 and R5 are each independently selected from:
- an aliphatic group,
- a further moiety of the formula (II), or
- a unit containing an acrylate or other functional group that is curable in a free radical curing reaction.
