<P>PROBLEM TO BE SOLVED: To provide a resin composition for reflectors, which can prevent the lowering in the reflection coefficients of the reflectors by thermal treatments, when LED is sealed and can reduce the water absorption coefficients of the reflectors. <P>SOLUTION: This resin composition for the reflectors comprises (1) 30 to 99 wt.% of a styrenic polymer having a syndiotactic structure and (2) 1 to 70 wt.% of a white pigment. By using the styrenic polymer having a syndiotactic structure, the lowering in the reflection coefficients of the reflectors in sealing processes can be inhibited. <P>COPYRIGHT: (C)2007,JPO&INPIT |
