Polyurethane polyisocyanate, method for producing polyurethane polyisocyanate, polyisocyanate composition, adhesive, layered product, and packaging material

Abstract

Provided is a polyurethane polyisocyanate that is less colored even when the content of unreacted isocyanate monomers is removed by distillation. A polyisocyanate composition (X) contains a polyurethane polyisocyanate (A1) which is a reaction product of a diisocyanate monomer (l) and a polyol compound (m), 0.1 mass % or less of a diisocyanate monomer (l′), sodium, and magnesium. The sodium has a content of 100 ppb or more and 700 ppb or less of the polyurethane polyisocyanate (A1), the magnesium has a content of 10 ppb or more and 50 ppb or less of the polyurethane polyisocyanate (A1), and the sodium and the magnesium have a mass ratio Na/Mg of 2 or more and 70 or less.

Dependencies are inferred from the claim text.
