First claim
Opening claim text (preview).
What is claimed is: 1. A resin composition comprising: a polylactic acid resin or cellulose resin, 0.07 phr to 8 phr of lignin, and 4 phr to 30 phr of an aromatic condensed phosphoric acid ester, wherein a weight-average molecular weight of the lignin is in a range of from 5000 to 10000. 2. The resin composition according to claim 1 , wherein a weight ratio of the lignin to the aromatic condensed phosphoric acid ester is in a range of from 1:1 to 1:200. 3. The resin composition according to claim 1 , wherein an amount of the aromatic condensed phosphoric acid ester is from 5 phr to 20 phr. 4. The resin composition according to claim 1 , wherein an amount of lignin is from 0.1 phr to 5 phr. 5. The resin composition according to claim 1 , wherein a content of the polylactic acid resin or cellulose resin is in a range of from 72% by weight to 95% by weight, based on the total resin composition. 6. A resin composition comprising: a crosslinked polymer compound formed from a polylactic acid resin or cellulose resin and 0.07 phr to 8 phr of lignin, and 4 phr to 30 phr of an aromatic condensed phosphoric acid ester. 7. The resin composition according to claim 6 , wherein an amount of lignin is from 0.1 phr to 5 phr. 8. The resin composition according to claim 6 , wherein a weight ratio of the lignin to the aromatic condensed phosphoric acid ester is in a range of from 1:1 to 1:200. 9. The resin composition according to claim 6 , wherein an amount of the aromatic condensed phosphoric acid ester is from 5 phr to 20 phr. 10. The resin composition according to claim 6 , wherein a weight-average molecular weight of the lignin is in a range of from 5000 to 10000. 11. The resin composition according to claim 6 , wherein a content of the polylactic acid resin or cellulose resin is in a range of from 72% by weight to 95% by weight, based on the total resin composition. 12. A resin molded article comprising: a crosslinked polymer compound formed from a polylactic acid resin or cellulose resin and 0.07 phr to 8 phr of lignin, and 4 phr to 30 phr of an aromatic condensed phosphoric acid ester. 13. The resin molded article according to claim 12 , wherein an amount of lignin is from 0.1 phr to 5 phr. 14. The resin molded article according to claim 12 , wherein a weight ratio of the lignin to the aromatic condensed phosphoric acid ester is in a range of from 1:1 to 1:200. 15. The resin molded article according to claim 12 , wherein an amount of the aromatic condensed phosphoric acid ester is from 5 phr to 20 phr. 16. The resin molded article according to claim 12 , wherein a weight-average molecular weight of the lignin is in a range of from 5000 to 10000.
