The present invention is to provide an aqueous resinndispersion containing polyester resin having a low acidnvalue and a high-molecular weight that is excellent innstorage stability and can form a resin film superior innfilm properties such as adhesiveness to base materials,nwater resistance, solvent resistance, processability, andnthe like, and a process for producing the same. n The present invention relates to a polyester resinnaqueous dispersion, comprising: a polyester resin (A)nhaving an acid value of 2 mg KOH/g or more and less than 8nmg KOH/g and a number-average molecular weight of 5,000 ornmore; a basic compound (B); and water (C), wherein thencontent of the polyester resin (A) is 1 to 70 percent bynmass, the content of water (C) is 10 percent by mass ornmore, and no surfactant is contained, and a process fornproducing the polyester resin aqueous dispersion by phase-inversionnemulsification, wherein the phase-inversionnemulsification is carried out at a temperature of 40°C ornlower. |
