<p>Disclosed is a biodegradable resin composition containing a biodegradable resin, a plasticizer and a crystal nucleator. The plasticizer is composed of a compound having two or more ester groups in a molecule wherein at least one of the alcohol components constituting an ester is added with 0.5-5 moles of an alkylene oxide having 2-3 carbon atoms per one hydroxy group on average, and the crystal nucleator is a mixture of the following crystal nucleator (1) and the following crystal nucleator (2). The crystal nucleator (1) is composed of the following crystal nucleator (1-1) or the following crystal nucleator (1-2). Crystal nucleator (1-1): atleast one compound selected from compounds having a hydroxy group and an amide group in a molecule Crystal nucleator (1-2): at least one ester selected from hydroxy fatty acid esters The crystal nucleator (2) is composed of at least one compound selected from the group consisting of phenylphosphonic acid metal salts, metal salts of phosphate esters, metal salts of aromatic sulfonic acid dialkyl esters, metal salts of rosin acids, aromatic carboxylic acid amides, rosin acid amides, carbohydrazides, N-substituted ureas, salts of melamine compounds and uracils.</p> |
