Summary: | The present invention improves the miscibility of a polyurethane resin composition, which contains an inorganic filler, with a polyol-containing composition, while suppressing a decrease in the storage stability of an isocyanate-containing composition. An isocyanate-containing composition according to one embodiment of the present invention is to be used as a polyisocyanate component for a two-pack type reactive polyurethane resin composition, and contains: an isocyanate group-containing urethane prepolymer that is obtained by causing a reaction between a polyisocyanate and a polyol having an average number of functional groups of 2.5 or less and a weight average molecular weight of 700 or more; an inorganic filler; a plasticizing agent; and a silane coupling agent that does not contain an active hydrogen group. |
