Two-component polyurethane adhesive composition for film lamination

A two-component polyurethane adhesive composition comprising a polyol component and an isocyanate component, wherein

• the polyol component comprises at least one polyester polyol obtained from a reaction mixture comprising, based on the total weight of the reaction mixture,
• from 1% to 25% by weight of at least one cycloaliphatic polyol,
• from 1% to 40% by weight of at least one heterocyclic polyol,
• from 1% to 40% by weight of at least one linear or branched aliphatic polyol, and
• from 30% to 70% by weight of at least one polyfunctional carboxylic acid, and
• the isocyanate component comprises at least one alkoxysilane functionalized isocyanate compound having no epoxide group,
• wherein the cycloaliphatic polyol is selected from 1,4-cyclohexanedimethanol, cyclobutanediol, cyclopentanediol, 1,4-cyclohexanediol, cycloheptanediol, cyclooctanediol, cyclohexanedimethanol, tricyclo[5.2.1.0.2.6]decanedimethanol, bicyclo[4.3.0]-nonanediol, dicyclohexanediol, tricyclo[5.3.1.1]dodecanediol, bicyclo[4.3.0]nonanedimethanol, tricyclo[5.3.1.1]dodecanediethanol, spiro[3.4]octanediol, butylcyclohexanediol, 1,1′-bicyclohexylidenediol, cyclohexanetriol, hydrogenated bisphenol A, 1,3-adamantanediol, and mixtures thereof.
