Title:
LOW HUE POLYESTER RESIN COMPOSITION AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2004346150
Kind Code:
A
Abstract:
To provide a polyester resin composition which has excellent hue heat stability and has flexibility and thixotropy.
The polyester resin composition is obtained by polymerizing a polycarboxylic acid mixture comprising a content of 1,3,6-hexanetricarboxylic acid of ≥80 mass%, a content of adipic acid of ≤10 mass%, a content of 3-carboxymethyl-1,5-pentanedicarboxylic acid of ≤10 mass%, and an RI (refractive index) detection component of ≤0.5 mass% as a polymerizable monomer component, and the lightness index L of an aqueous solution obtained by dissolving 0.400 g polycarboxylic acid mixture in 4.0 ml distilled water is ≥98, and the chromaticness index a is -2.0 to 2.0 and the chromaticness index b is -2.0 to 3.0.
