Title:
POLYESTER FOR BINDER AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH0597985
Kind Code:
A
Abstract:
PURPOSE:To obtain a polyester for binder, consisting of a hexamethylene terephthalate based polyester obtained by copolymerizing a specific copolymer component using a specific catalyst. CONSTITUTION:When a polyester for binder being >=0.5 in intrinsic viscosity and consisting of (A) an acid component containing A1: 65-90mol% terephthalic acid and A2: 35-10% 2, 6naphthalene dicarboxylic acid and (B) a glycol component containing B1: >=80% hexamethylene glycol and B2: 0.1-1% monofunctional polyoxyalkylene glycol expressed by the formula and having 100-3000 average molecular weight and, a reaction product of an alkyltitanate and/or its condensate and an organic carboxylic acid and/or its acid anhydride is as a polycondensation catalyst and an alkylsulfonic acid metal salt 1/40 to 20 times by mol based on Ti in a main product of the reaction is used as a hue improver.
