(57) [Summary] [PROBLEMS] To improve the water resistance, oil resistance, air-tightness, etc. of textiles and paper products, and to improve the properties of textiles and paper products by using it for coating textile products and paper products. Provided is a biodegradable resin aqueous emulsion having stable dispersibility without lowering the biodegradability of paper and paper products. SOLUTION: The aqueous biodegradable resin dispersion of the present invention is characterized in that the acetylcellulose-based biodegradable resin is dispersed and stabilized in water. A stabilizer containing a cationic polymer compound having an average molecular weight of 300,000 or more or an anionic polymer compound having an average molecular weight of 300,000 or more and polyvinyl alcohol is preferable. |
