ADHESIVE FOR LAMINATE

摘要

PROBLEM TO BE SOLVED: To obtain an adhesive for a laminate in which a low-molecular weight compound eluted in contents in a laminate film and performances that the contents essentially have are not impaired. SOLUTION: In this adhesive for laminate, a polyester polyol is mixed with a naphthalenedicarboxylic acid and/or its alkyl ester and the concentration of a cyclic ester compound calculated as dibutyl phthalate value extracted from the laminate film bonded by the adhesive for a laminate in extraction water extracted with water having 0.5 mL/cm2 per unit area of the laminate film measured by gas chromatography flame ionization detector is <=0.5 ppb.
