FIELD: layered products.
SUBSTANCE: invention relates to a two-component polyurethane adhesive composition for producing laminar materials, a multilayer layered material and a method for production thereof, as well as use of a two-component polyurethane adhesive composition. Two-component polyurethane adhesive composition contains a binding component and a curing component containing a polyester with terminal hydroxy groups. Binding component contains a polyurethane prepolymer with terminal NCO-groups. Polyurethane prepolymer is obtained by reacting a polyol mixture with at least one polyisocyanate. Polyol mixture contains (a) 0.1 to 20.0 wt. % at least one polybutadiene polyol with respect to the total weight of the polyol mixture, and (b) from 5.0 to 99.9 wt. %. of at least one polyether polyol with respect to total weight of polyol mixture. Polyether polyol contains at least one polyether polyol with number-average molecular weight Mn in the range of >1000 g/mol to 10,000 g/mol. Polyisocyanate is used in such amount that isocyanate groups are present in molar excess relative to hydroxyl groups of polyol mixture. Method of producing multilayer layered material consists in the fact that at least two films are glued layer-by-layer using said gluing composition. Multilayer layered material is used for packing of food products.
EFFECT: invention enables to obtain an adhesive composition which does not contain a solvent and which has improved adhesion to films with low surface energy.
