Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a hot-melt adhesive that is solvent-free, does not remain in the environment after disposal, because it is biodegradable and can be readily applied in no need of special installation. SOLUTION: A biodegradable polyester resin is emulsified by using an emulsifier and the carboxylic acid groups in the resin are neutralized with an alkaline substance to obtain a biodegradable resin emulsion. Coating film layers, sheets or fine particles are formed from the neutralized biodegradable resin emulsion composition and they are used as the hot-melt adhesive.
