PURPOSE: The titled resin of small particle size excellent in stability, which is prepd. by compounding a metal sulfonate group-contg. polyester resin, a water- soluble org. compd. and water in a specifiec proportion. n CONSTITUTION: A metal sulfonate group-contg. polyester resin MW 2,500W30,000 and softening pt. 40W200°C composed of a dicarboxylic acid component consisting of 11W100mol% metal sulfonate group-contg. arom. dicarboxylic acid, 89W0mol% arom. dicarboxylic acid contg. no metal sulfonate group and 50W0mol% aliph. or alicylic dicarboxylic acid, and a glycol component consisting of 10W100mol% 2W8C aliph. glycol and/or 6W15C alicyclic glycol and 90W0mol% adduct of bisphenol A with ethylene or propylene oxide, is used. Said polyester resin (A), an org. water- soluble compd. (B) such as propanol and water (C) are compounded in a wt. ratio of formulasI, II and III. n COPYRIGHT: (C)1982,JPO&Japio |
