    Abstract: PROBLEM TO BE SOLVED: To provide a reaction injection molded article having no air bubbles in the inside of the molded article without imposing an undue burden on equipment and with a simple formulation.
    SOLUTION: A reactive stock solution (A) for reaction injection molding is used for reaction injection molding by subjecting a norbornene-based monomer to bulk polymerization within a mold and comprises at least a norbornene-based monomer, a non-basic filler and a Shiff base coordinated metathesis polymerization catalyst represented by formula (1). A reaction injection molding method comprises injecting a blending solution comprising as an essential component the reactive stock solution for reaction injection molding (A) into a mold and carrying out bulk polymerization within the mold. A reaction injection molded article is produced by the reactive injection molding method.

    Abstract: PROBLEM TO BE SOLVED: To provide an in-mold coating method capable of forming an even cover coating film without causing a non-coated defective portion even if a coated object is a big molding and a coated molding obtained thereby.
    SOLUTION: In-mold coating method that injects a cover into a cover coating space formed by a resin molding and a mold from cover injection ports provided at the mold to form a cover layer on a surface of the resin molding, after forming a resin where a resin material is injected into a cavity formed by the mold of a pair of male mold and female mold, wherein a surface area of the cover coating on the resin molding is 2 m
    2 or more, a settling starting time at 90°C thereof is 60 seconds or more and 200 seconds or less, a cover with a viscosity of 3,500 Pa/s or less is used, and the cover injection ports are provided so as to allow the shortest flowing distance to be 1.3 m or less out of distances between all points in the cover coating space and each of the cover injection ports.
