Abstract

A polyisocyanate composition comprising a product which is obtained by reacting diphenylmethane diisocyanate having a 2,4'-diphenylmethane diisocyanate content of 55 to 90% by mass with polyoxyethylene-polyoxypropylene polyol having an oxyethylene content of 1 to 40% by mass, an average hydroxyl equivalent of 700 to 2500, and a nominal average functionality of 2 to 6 and which has an isocyanato group content of 15 to 30% by mass.
