Abstract

The present invention provides a resin composition capable of forming a film exhibiting a small humidity-dependent variation in optical values; a triazole compound to be incorporated into the resin composition; an optical film and an optical lens, each of which is prepared from the resin composition and exhibits a small humidity-dependent variation in optical values; and a polarizing plate, a circularly polarizing plate, and an image display device, each of which includes the optical film and exhibits excellent moisture resistance. The resin composition of the present invention contains a resin and a compound having a 5-membered or 6-membered aromatic hydrocarbon or heterocyclic ring, wherein the resin is a hygroscopic resin, the compound has at least three specific aromatic rings having a specific NICS value, and the specific aromatic rings are bonded to one another via a single bond or one or two atoms.

First claim

The invention claimed is:

1. A resin composition comprising:
a resin and
a compound which has a structure represented by the following formula:

wherein A 1 , A 2 and A 3 each independently represent an alkyl group, a cycloalkyl group, an aromatic hydrocarbon ring, or an aromatic heterocyclic ring; T 1 , T 2 and T 3 each independently represent a pyrrole ring, a pyrazole ring, an imidazole ring, a 1,2,3-triazole ring, or a 1,2,4-triazole ring; L 1 , L 2 , L 3 , L 4 , L 5 and L 6 each independently represent a single bond or a divalent linking group; and m represents an integer of 0 to 4.

2. The resin composition according to claim 1 , wherein the resin is a hygroscopic resin.

3. The resin composition according to claim 2 , wherein the hygroscopic resin exhibits a water absorption of 0.5 to 10 mass % at 23° C.

4. The resin composition according to claim 2 , wherein the hygroscopic resin is a cellulose compound.

5. The resin composition according to claim 2 , wherein the hygroscopic resin is a cellulose ester.

6. The resin composition according to claim 1 , wherein the compound has a pyrrole ring, a pyrazole ring, an imidazole ring, a 1,2,3-triazole ring, or a 1,2,4-triazole ring having a nucleus-independent chemical shift value smaller than that of a benzene ring.

7. A resin composition comprising a resin and a compound having a formula selected from the group consisting of
