Abstract:
A surface ornament composition for a part of a fishing tackle or a bicycle is provided in which a vivid surface ornament composition having sufficient corrosion resistance and toughness can be attained without using an apparatus with a large scale. An inner coating layer is laminated on the surface of a part made of fiber reinforced plastics, a silver thin film coating layer is laminated on the inner coating layer and an outer coating layer is laminated on the silver thin film coating layer. The inner coating layer and the outer coating layer are formed by use of any one selected from resin paint of two-part type formed by urethane reaction of isocyanate group and hydroxyl group, resin paint of two-part type formed by reaction of resin having amino group and silicon compound having epoxy group and resin paint of two-part or three part type in which the above two reactions are simultaneously generated. The silver thin film coating layer is formed of metal complex of silver with amine as ligand that is heated after having been applied.
