FIELD: adhesive compositions.

SUBSTANCE: described is a two-component adhesive composition for producing a laminate comprising (I) an isocyanate component having from 12 % to 19 % by weight of isocyanate groups and viscosity at 25 °C equal to 5500 MPa·s, containing a prepolymer with an isocyanate functional group, which is a reagent reaction product, containing (A) one or more isomers of diphenylmethane diisocyanate and (B) one or more polyether polyols, one or more polyester polyols and mixtures thereof, and (II) a polyol component containing: (A) up to 50 wt % of one or more polyether polyols based on weight of said polyol component, wherein said polyether polyol has kinematic viscosity at 25 °C 25 centistokes (cSt) or more, (B) 30 wt % or more of one or more fatty triglycerides of weight of said adhesive composition, wherein said fatty triglyceride has one or more side hydroxyl groups and (C) a UV absorber and a sterically hindered amine light stabilizer. Described also is a method of producing a laminate using said adhesive composition and a laminate.

EFFECT: technical result is obtaining a composite and a laminate with reduced yellowing when exposed to ultraviolet radiation.
