PROBLEM TO BE SOLVED: To provide a solventless-type resin composition for bonding laminated sheets, which can manifest adhesive strength equal to or better than before in a shorter aging time without rigorously controlling environmental moisture, and has a long pot life and high workability.SOLUTION: Provided is a resin composition for bonding laminated sheets, comprising a polyisocyanate component (A), a polyol component (B), and 0.03 to 2 wt.% of water (C) in 100 wt.% of the resin composition for bonding laminated sheets. An equivalent ratio (isocyanate groups/hydroxyl groups) of isocyanate groups in the polyisocyanate component (A) to hydroxyl groups in the polyol component (B) is 0.5 to 2.5. An equivalent ratio of the isocyanate groups in the polyisocyanate component (A) to the number of moles of the hydroxyl groups in a polyol component (B) and water (C) in the resin composition for bonding laminated sheets, (isocyanate groups/(hydroxyl groups+water)), is 2.3 to 0.5. |
