2. Description of the Related Art Conventionally, a casein-based adhesive has been used as an adhesive for labels such as glass bottles of beer, soft drinks, etc. However, since the adhesive is a natural product, it cannot be stored for a long time. There was a problem that the viscosity was lowered and the storage stability was not sufficient. On the other hand, it has been reported that an aqueous emulsion containing a synthetic resin such as an ethylene-vinyl acetate copolymer and poly (meth) acrylic acid has excellent storage stability and thus can be used as an adhesive for labels ( JP-A-5-230427).

An object of the present invention is to provide a resin composition for label bonding which has excellent storage stability and can be continuously and uniformly applied to a vertical rotating roll surface.

Under these circumstances, the inventors of the present invention have made extensive studies on an aqueous emulsion containing a synthetic resin, and as a result, have found that the aqueous emulsion contains a water-soluble polymer having a specific molecular weight. Resin composition,
In addition to solving such problems, a label adhered using the resin composition has an initial adhesiveness (adhesiveness immediately after application of an adhesive) and a normal adhesiveness (adhesive is dried, steady-state adhesiveness).
