| titleOfInvention | Method for producing polyester resin for reflector |
| abstract | Disclosed is a method for producing a polyester resin for a reflector for use in a polyester resin composition capable of producing a reflector having improved long-term thermal stability and weather resistance. The present invention relates to a method for producing a polyester resin for a reflector. In the above method, a polyvalent carboxylic acid component containing 95 mol% or more and 100 mol% or less of terephthalic acid or an ester-forming derivative thereof, and a polyhydric alcohol component containing a dialcohol having an alicyclic skeleton in the presence of a polymerization catalyst. A step of obtaining a polyester resin (A) by polycondensation reaction, and an alkali metal compound or an alkaline earth metal in an amount of 0.1 to 10000 ppm by mass with respect to the total mass of the polyester resin (A) Adding the compound (B) to the polyester resin (A). [Selection figure] None |
