Abstract
Provided is a surface-coated reinforcing material which, when used in a fluid composition for reaction injection molding, causes substantially no increase in the viscosity of said fluid composition and can be well dispersed therein, and can improve the rigidity of an article obtained by reaction injection molding the same. The surface-coated reinforcing material is provided, on the surface of a reinforcing material, with laminated coating layers consisting of one or more coating layers (A), which comprise a silane coupling agent (I) having at least one hydrocarbon group having a norbornene structure, and one or more coating layers (B), which comprise a coupling agent other than the silane coupling agent (I) and/or a fatty acid.
