  • Patent number: 10738190
    Abstract: A resin composition includes: (a) a supported platinum catalyst having a structure shown by the following general formula (1) in which a platinum complex is supported on a surface of an inorganic oxide; and (b) a thermoplastic matrix resin. The resin composition is usable as an addition-reaction catalyst capable of imparting sufficient storability and quick curability to an addition-reaction curable composition. In the formula, L represents a ligand selected from carbon monoxide, an olefin compound, an amine compound, a phosphine compound, an N-heterocyclic carbene compound, a nitrile compound, and an isocyanide compound; and n represents the number of Ls and an integer from 0 to 2.
