Solventless adhesive compositions and laminate materials prepared with the same

A solventless adhesive composition, comprising:

• (A) an isocyanate component comprising a prepolymer which is the reaction product of reactants comprising:
• (a) at least one monomeric cycloaliphatic isocyanate compound comprising at least one cyclohexyl(ene) group and at least two isocyanate groups, and (b) at least one first polyol selected from the group consisting of a first polyester polyol, optionally a first polyether polyol, optionally a first polycarbonate polyol, and combinations thereof, wherein the prepolymer comprises more than one free isocyanate groups;
• and
• (B) a polyol component comprising at least one second polyol selected from the group consisting of a carboxylic acid functionalized-polyol having hydroxyl group and acid side group, a phosphorous-functionalized polyol comprising at least one phosphate ester group, a second polyester polyol, a second polyether polyol, and any combinations thereof,
• wherein the (B) polyol component comprises from 20 to 60 wt % of the second polyester polyol, from 30 to 70 wt % of the second polyether polyol, from 1 to 20 wt % of the phosphorous-functionalized polyol, and from 0 to 30 wt % of the carboxylic acid functionalized-polyol, based on the total weight of the (B) polyol component.
