Abstract

Provided is an unsaturated double bond-containing compound capable of sufficiently advancing a crosslinking reaction or a curing reaction when used for a coating material or the like and having oxygen absorption performance. The present invention also provides an oxygen absorbent containing the unsaturated double bond-containing compound and a resin composition containing the same. Provided are an unsaturated double bond-containing compound represented by general formula (I), an oxygen absorbent containing the same, and a resin composition.

First claim

The invention claimed is:

1. An unsaturated double bond-containing compound represented by the following general formula (I):

wherein:
X and Y each independently represent a chalcogen atom;
R 1 , R 2 , R 7 , and R 8 each independently represent any one selected from the group consisting of an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an aryl group, and an aralkyl group;
R 3 , R 4 , R 5 , and R 6 each independently represent any one selected from the group consisting of a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an aryl group, and an aralkyl group;
J represents a linking group composed of an aliphatic hydrocarbon having 3 to 15 carbon atoms,
wherein any carbon atom of the linking group is optionally substituted with an oxygen atom, and
wherein the linking group has at least one substituent selected from the group consisting of a (meth)acryloyloxy group, a styryloxy group, and an alkenyloxy group having 2 to 5 carbon atoms;

n is an arbitrary integer of 1 to 5; and
when a plurality of Y, R 5 , R 6 , R 7 , and R 8 are present, they are each optionally different atoms or groups.

2. The unsaturated double bond-containing compound according to claim 1 , wherein X in the general formula (I) is an oxygen atom.

3. The unsaturated double bond-containing compound according to claim 1 , wherein R 3 and R 6 in the general formula (I) are a hydrogen atom.

4. The unsaturated double bond-containing compound according to claim 1 , wherein R 4 and R 5 in the general formula (I) are each independently a hydrogen atom or a methyl group.

5. An unsaturated double bond-containing compound represented by the following general formula (II):

wherein:
R 9 represents a hydrogen atom or a methyl group;
R 10 represents any one selected from the group consisting of a hydroxy group, a (meth)acryloyloxy group, a styryloxy group, and an alkenyloxy group having 2 to 5 carbon atoms; and
R 11 , R 12 , R 13 , and R 14 each independently represent any one selected from the group consisting of an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an aryl group, and an aralkyl group.

6. The unsaturated double bond-containing compound according to claim 5 , wherein R 9 in the general formula (II) is a hydrogen atom.

7. An oxygen absorbent comprising the unsaturated double bond-containing compound according to claim 5 .

8. The oxygen absorbent according to claim 7 , comprising 0.001 to 10 mol % of a transition metal salt with respect to the vinyl group in the unsaturated double bond-containing compound.

9. A resin composition, comprising the oxygen absorbent according to claim 7 and a resin.

10. The resin composition according to claim 9 , wherein the resin is an active energy ray-curable resin.
