The present invention relates to fiber-reinforced thermoplastic resin composition comprising 0.1 to 10 mass % of a (meth)acrylic-based polymer, 1 to 70 mass % of reinforcing fiber, and 20 to 98.9 mass % of thermoplastic resin, wherein the (meth)acrylic-based polymer has, in a side chain, at least one functional group selected from a hydroxyl group, a carboxyl group, an amide group, and an urea group, and has a cohesive energy density (CED) of 385 to 550 MPa. The present invention provides, particularly in the case of using a polyolefin-based resin as matrix resin, a fiber-reinforced thermoplastic resin composition and a reinforcing fiber bundle which have high adhesiveness and good mechanical characteristics.

Fiber-reinforced thermoplastic resin composition, reinforcing fiber bundle, and process for production of fiber-reinforced thermoplastic resin composition

A curable coating composition is provided which comprises an acrylic resin having an epoxy group and a hydroxyl group in the side chain (A) and a compound having an amino group (B). The composition may further comprise a silane compound having an epoxy group or an amino group in the molecule (C).

Curable coating composition

This invention relates to a coating resin composition including an acrylic resin (A) having a hydroxyl group and an alicyclic epoxy group attached to side chains thereof, an alicyclic epoxy resin (B) having an epoxy equivalent weight of 100-1000, an organoalkoxy silane compound (C) having a glycidyl group and a hydrolyzable alkoxy silane group contained in one molecule thereof, and an aluminum chelate compound (D). The composition is stably storable, highly curable at low temperature (80&deg; C. or below) and capable of producing a highly weatherable coating, and is useful particularly as a coating resin composition of a one-pack type and a coating derivable therefrom. The composition also exhibits various superior coating performance characteristics (bonding, appearance, weathering resistance, chemical resistance, solvent resistance and the like) in a well-balanced state.
