FIELD: chemistry.
SUBSTANCE: invention relates to an adhesive composition for the production of laminates. Polyurethane adhesive composition comprises a polyurethane dispersion and from 1.2 to 20 %, based on the dry weight relative to the total dry weight of the polyurethane dispersion, a polyisocyanate crosslinker. Polyurethane dispersion is the reaction product, based on the dry weight relative to the total dry weight of the polyurethane dispersion, from 10 to 40 % of a monomeric aromatic diisocyanate, from 30 to 65 % of a polyether polyol, from 15 to 30 % of a polyester polyol comprising at least one aliphatic group and one aromatic group, 0.1 to 8 % of a polyamine and 0.5 to 10 % of an ionic surfactant.
EFFECT: polyurethane adhesive composition is provided.
