    摘要: A phosphite of formula (I):
    wherein R 1 , R 2 , R 4 and R 5 represent hydrogen atom, an alkyl group, a cycloalkyl group, an alkylcycloalkyl group, an aralkyl group or a phenyl group; R 3 represents hydrogen atom or an alkyl group; X represents a direct bond, sulfur atom, or a -CHR 6 - group in which R 6 represents hydrogen atom, an alkyl group or a cycloalkyl group; A represents an alkylene group having 2 to 8 carbon atoms or a *-COR 7 -group in which R 7 represents a direct bond or an alkylene group, and * indicates the bond to the oxygen; and one of Y and Z represents a hydroxyl group, an alkoxy group or an aralkyloxy group and the other one represents hydrogen atom or an alkyl group, is suitably used as a stabilizer for an organic material.
