A resin composition contains a polyester polyol and a smectite with partially immobilized lithium.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resin composition comprising a polyester polyol and a smectite with partially immobilized lithium, wherein the polyester polyol has a hydroxyl value of 20 to 300 mg KOH/g. 2. The resin composition according to claim 1 , further comprising a curing agent. 3. The resin composition according to claim 2 , wherein the curing agent is a polyisocyanate. 4. The resin composition according to claim 1 , wherein the polyester polyol is a polycondensate of at least one polyfunctional carboxylic acid that includes at least one of ortho-oriented aromatic dicarboxylic acids and anhydrides thereof with a polyhydric alcohol. 5. The resin composition according to claim 1 , wherein the polyester polyol has a glycerol backbone. 6. The resin composition according to claim 1 , further comprising a coupling agent. 7. The resin composition according to claim 1 , wherein the smectite with partially immobilized lithium has a cation exchange capacity of 1 to 70 meq/100 g. 8. The resin composition according to claim 1 , wherein the smectite with partially immobilized lithium is present in an amount of 3% to 50% by mass based on total nonvolatile content of the resin composition. 9. An article molded from a resin composition according to claim 1 . 10. A laminate comprising a substrate and a molded article according to claim 9 on the substrate. 11. A gas barrier material comprising a resin composition according to claim 1 . 12. A coating material comprising a resin composition according to claim 1 . 13. An adhesive comprising a resin composition according to claim 1 . 14. A resin composition comprising a polyester polyol and a smectite with partially immobilized, wherein the smectite with partially immobilized lithium has a cation exchange capacity of 1 to 70 meq/100 g. 15. The resin composition according to claim 14 , further comprising a curing agent. 16. The resin composition according to claim 14 , wherein the polyester polyol has a hydroxyl value of 20 to 300 mg KOH/g. 17. An article molded from a resin composition according to claim 14 . 18. A resin composition comprising a polyester polyol and a smectite with partially immobilized, wherein the polyester polyol has a glycerol backbone. 19. The resin composition according to claim 18 , further comprising a curing agent. 20. An article molded from a resin composition according to claim 18 .
