Patent ID: 8748520

Claim:
A polycarbonate resin composition comprising a compound represented by the following formula (1), a phosphorous-based stabilizer and a hindered phenol-based stabilizer: wherein each of R 1a , R 1b , R 1c , R 1d and R 1e independently represents a hydrogen atom or a monovalent substituent provided that OH is excluded, at least one of the substituents represents a substituent having a Hammett's σp value of 0.3 or more, and the substituents may be combined each other to form a ring; and each of R 1g , R 1h , R 1i , R 1h , R 1k , R 1m , R 1n and R 1p , wherein the substituent having a Hammett's σp value of 0.3 or more is a group selected from the group consisting of COOR r , CONR s 2 , a cyano group, CF 3 , a nitro group and SO 3 M wherein each of R r and R s represents a hydrogen atom or a monovalent substituent, and M represents a hydrogen atom or an alkali metal, and wherein said monovalent substituent is an alkyl group having a carbon number of 1 to 20, a cyano group, a carboxyl group, an alkoxycarbonyl group, a carbamoyl group, an alkylcarbonyl group, a nitro group, an amino group, a hydroxy group, an alkoxy group having a carbon number of 1 to 20, an aryloxy group, a sulfamoyl group, a thiocyanate group, or an alkylsulfonyl group, and in the case of having a substituent, the substituent is an alkyl group having a carbon number of 1 to 20, a cyano group, a carboxyl group, an alkoxycarbonyl group, a carbamoyl group, an alkylcarbonyl group, a nitro group, an amino group, a hydroxy group, an alkoxy group having a carbon number of 1 to 20, an aryloxy group, a sulfamoyl group, a thiocyanate group, or an alkylsulfonyl group.
