Patent ID: 8426549

Claim:
A reflector obtained by molding a polyamide resin composition for reflectors, wherein the polyamide resin composition comprises 30 to 80% by weight of a polyamide resin (A), 10 to 60% by weight of an inorganic filler (B) and 5 to 50% by weight of a white pigment (C), with the proviso that the total of the components (A), (B) and (C) is 100% by weight, wherein the polyamide resin (A) comprises dicarboxylic acid component units (a-1) comprising 30 to 100% by mol of dicarboxylic acid component units derived from terephthalic acid and 0 to 70% by mol of component units derived from an aromatic dicarboxylic acid other than terephthalic acid and/or 0 to 70% by mol of component units derived from an aliphatic dicarboxylic acid of 4 to 20 carbon atoms, and diamine component units (a-2) comprising component units derived from a straight-chain aliphatic diamine of 6 to 12 carbon atoms and/or component units derived from an aliphatic diamine having a side chain and having 6 to 12 carbon atoms, and the polyamide resin (A) has a terminal amino group concentration of 70 to 230 mmol/kg and an intrinsic viscosity [η] of 0.5 to 0.9 dl/g and a melting point of 270 to 350° C., wherein the reflector has a reflectance retention of not less than 55%.
