FIELD: chemistry.
SUBSTANCE: invention relates to an adhesive composition based on aqueous polyurethane dispersion. The adhesive composition contains polyurethane prepolymer dispersed in an aqueous medium. Polyurethane prepolymer contains: isocyanate and crystalline linear polyether polyol obtained from caprolactone monomer having average molecular weight of 3000 g/mol and having a hydroxyl content of 20 to 150 mg KOH/g and a melting point less than or equal to 90°C.
EFFECT: improvement in barrier properties, an increase in the safety and effectiveness of laminating adhesives.
