ABSTRACT:
A laminate adhesive that can suppress elution of a low molecular weight compounds of a composite film into the content, so as to prevent the inherent properties or performances of the content from being spoiled by the low molecular weight compounds. In the laminate adhesive, the polyester polyol contains naphthalenedicarboxylic acid and/or alkyl ester thereof as an acid component, and concentration of cyclic ester compounds in extracted water, which are extracted from a composite film bonded by the laminate adhesive by water of 0.5 mL/cm2per unit area of the composite film, is 0.5 ppb or less in terms of dibutyl phthalate concentration measured by a gas chromatograph-flame ionization detector.
