Abstract
An object of the present invention is to provide an emulsion-based adhesive having excellent adhesive force, excellent heat resistance of adhesive force, excellent holding power, less adhesive residue and good “tack”.According to the present invention, an emulsion-based adhesive comprising: a styrene-butadiene rubber; a natural rubber; and a tackifier, wherein a gel fraction of the styrene-butadiene rubber is 20 to 60% by mass, a content of the natural rubber with respect to 100 parts by mass of the styrene-butadiene rubber is 10 to 35 parts by mass, a content of the tackifier with respect to 100 parts by mass of the styrene-butadiene rubber is 100 to 150 parts by mass, and a ratio of a styrene monomer unit in a total amount of the styrene-butadiene rubber and the natural rubber contained in the adhesive is 5 to 15% by mass, is provided.
