摘要： A biodegradable resin composition may include a polyester resin and one or more nitrogen compounds of formula (I):




R, R″, and R″″ each independently being H or a monovalent organic group which may have a substituent group which does not form a ring structure with each other, optionally in salt form (excluding (RS)-1-methyl-2-nitro-3-[(3-tetrahydrofuryl)methyl]guanidine, and/or compounds of formula NH2—CHR—COOH, with R being H or a monovalent aliphatic hydrocarbon group, and phenylalanine). The polyester resin may be a resin having dicarboxylic acid unit and a diol unit. The content of the compound of formula (I) may be in a range of from 0.1 to 70 wt. %. The concentration of nitrogen atom in the compound of formula (I) may be 6 wt. % or more. The molecular weight of the compound of formula (I) may be less than 10000.
