<P>PROBLEM TO BE SOLVED: To provide a resin composition for an LED reflector that is superior in heat-discoloration resistance, inexpensive, and easy to handle and work with. <P>SOLUTION: The resin composition contains at least an unsaturated polyester resin, a polymerization initiator, an inorganic filler, a white pigment, a release agent, and a stiffener. The resin composition is a dry composition which stays solid in a temperature range of 30°C or below. The dry unsaturated polyester resin composition is a mixture of an unsaturated alkyd resin and a cross-linking agent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
