FIELD: technological processes.
SUBSTANCE: invention can be used for lamination of flexible films and aluminum foil. Two-component composition of the binding agent contains a first component and a second component containing a water-dispersible polyisocyanate. First component is an aqueous mixture containing a water-dispersible polyether polyol, a rosin resin and a polymer based on styrene and acrylic monomers. Water-dispersible polyisocyanate is selected from polyisocyanates based on toluene diisocyanate, isophorone diisocyanate, hexamethylene diisocyanate, diphenylmethane diisocyanate, isomers thereof and mixtures thereof. Second component is present relative to the first component in molar ratio of NCO/NCO-reactive group from 1:1 to 8:1. Invention also discloses a method of making a multilayer article and a laminar material.
EFFECT: invention provides improved strength of the weld at high temperatures.
