Abstract

The present invention aims to provide a composition capable of forming a coat which has a good effect of preventing corrosion of metal and is excellent in adhesiveness with metal, transparency, and insulation. The composition of the present invention includes a fluoropolymer having at least one group selected from the group consisting of polymerizable functional groups and cross-linkable functional groups, and a nitrogen-containing aromatic heterocyclic compound having a polymerizable functional group.

First claim

The invention claimed is:

1. A composition comprising:
a fluoropolymer having at least one group selected from the group consisting of polymerizable functional groups and cross-linkable functional groups; and
a nitrogen-containing aromatic heterocyclic compound having a polymerizable functional group,
wherein the nitrogen-containing aromatic heterocyclic compound is a compound represented by the following formula (1) or the following formula (2):

wherein the ring A represents a substituted or unsubstituted 5- or 6-membered nitrogen-containing aromatic heterocycle; R 1 represents a hydrogen atom, a halogen atom, or a C 1-6 alkyl group; n1 is an integer of 1 to 6; L 1 represents a linking group having a valency of n1+1 and having a bond represented by —CO—NH—, —CO—O—, —O—CO—NH—, or —NH—CO—NH—; and the ring B represents a substituted or unsubstituted aromatic ring,

wherein the ring C represents a substituted or unsubstituted 5- or 6-membered nitrogen-containing aromatic heterocycle; R 2 represents a hydrogen atom, a halogen atom, or a C 1-6 alkyl group; n2 is an integer of 1 to 6; and L 2 represents a linking group having a valency of n2+1 and having a bond represented by —CO—NH—, —CO—O—, —O—CO—NH—, or —NH—CO—NH—.

2. The composition according to claim 1 ,
wherein the fluoropolymer comprises a polymerization unit based on a monomer having at least one group selected from the group consisting of polymerizable functional groups and cross-linkable functional groups,
the at least one group selected from the group consisting of polymerizable functional groups and cross-linkable functional groups is at least one selected from the group consisting of a carbon-carbon double bond, a hydroxy group (excluding the hydroxy group contained in a carboxyl group), a carboxyl group, and an amino group.

3. The composition according to claim 1 ,
wherein, in the formula (1), the ring A is a 5-membered nitrogen-containing aromatic heterocycle having two or three nitrogen atoms.

4. The composition according to claim 1 ,
wherein, in the formula (1), L 1 is represented by the following formula (3):

wherein Q 1 represents —O— or —NH—; l1 is 0 or 1; m1 is an integer of 1 to 20; and n1 is an integer of 1 to 6, if m1 is 1, n1 is an integer of 1 to 3, and if m1 is 2, n1 is an integer of 1 to 5.

5. The composition according to claim 1 ,
wherein, in the formula (1), the ring B is an aromatic ring substituted with a hydroxy group, an amino group, a carboxylic acid group, a nitro group, a halogen group, a thiol group, a cyano group, an acyl group, a sulfonic acid group, a mesyl group, an alkyl group, or a substituent represented by the following formula (4):

wherein L 3 represents a linking group having a valency of n3+1 and having a bond represented by —CO—NH—, —CO—O—, —O—CO—NH—, or —NH—CO—NH—; R 3 represents a hydrogen atom, a halogen atom, or a C 1-6 alkyl group; and n3 is an integer of 1 to 6.

6. The composition according to claim 1 ,
wherein, in the formula (1), the ring B is a benzene ring.

7. The composition according to claim 1 ,
wherein, in the formula (2), the ring C is a 5-membered nitrogen-containing aromatic heterocycle having two or three nitrogen atoms.

8. The composition according to claim 1 ,
wherein, in the formula (2), L 2 is represented by the following formula (5):

wherein Q 2 represents —O— or —NH—; l2 is 0 or 1; m2 is an integer of 1 to 20; and n2 is an integer of 1 to 6, if m2 is 1, n2 is an integer of 1 to 3, and if m2 is 2, n2 is an integer of 1 to 5.

9. The composition according to claim 1 , further comprising an acrylic component (A).

10. The composition according to claim 1 , which is a coating material.

11. The composition according to claim 1 , which is an anti-corrosive coating material.

12. A coated article comprising:
a substrate; and
a coat formed from the composition according to claim 1 on the substrate.

13. The coated article according to claim 12 ,
wherein the substrate is formed from a metal.

14. A sheet formed from the composition according to claim 1 .

15. A laminated sheet comprising
