Abstract

Disclosed is a solventless adhesive composition comprising (A) an isocyanate component obtained by the reaction of reactants comprising at least one monomeric cycloaliphatic isocyanate compound comprising at least one cyclohexyl (ene) group and at least one first polyol; and (B) a polyol component comprising particularly selected functionalized and non-functionalized polyol. The solventless adhesive composition can be used for the production of laminate materials, e.g. laminate packing material, which well meet the requirements of various food compliance regulations and has superior performance properties such as heat and chemical resistance. A method for producing said laminate material and the resultant laminate material are also disclosed.
