<p>PURPOSE:An aqueous dispersion, prepared by incorporating a copolymer of a specific polyester with polyethylene glycol into a water-soluble organic compound and water, capable of forming films having improved water resistance, a fine particle diameter and improved storage stability. CONSTITUTION:An aquoue dispersion, prepared by incorporating (A) a polyether ester resin, having a molecular weight of 2500-40000, and obtained by copolymerizing a polyester segment consisting of a polycarboxylic acid component consisting of 40-99.9mol% aromatic dicarboxylic acid containing no metallic salt of sulfonic acid, 59.9-0mol% aliphatic or alicyclic dicarboxylic acid and 0.1- 2mol% aromatic dicarboxylic acid containing the metallic salt of sulfonic acid and a glycol component with at least 20wt%, based on the formed polymer, polyethylene glycol having a molecular weight of 500-5000 with (B) a water- soluble organic compound having a boiling point of 70-200 deg.C and (C) water. The mixing ratios of the respective components are as follows:(A)/(B)/(C)=(1- 60):(0-40):(20-99) and (B)/(C)=(0-50):(100-50).</p> |
