▎ 摘　　要

NOVELTY - Electroless plating comprises injection molding synthetic resin material, physically etching, degreasing by immersing resin material in degreasing solution containing monomethanolamine, pre-etching using 1,2-dimethoxypropane, ultrasonically cleaning, chemically etching, neutralizing, conditioning using polyoxyethylene alcohol, performing catalytic treatment by immersing in catalyst solution containing palladium chloride, hydroxylamine sulfate, hydroxybenzoic acid, and aqueous sulfuric acid solution, forming electroless nickel plating layer on surface of synthetic resin material by immersing in nickel plating solution containing nickel sulfate, sodium citrate, and sodium hypophosphite, forming pattern by irradiating laser and etching, immersing in activating solution containing hydrofluoric acid, sodium sulfate, and graphene oxide colloid, copper plating, chrome plating, peeling using nitric acid, washing and drying the peeled synthetic resin material with water. USE - The method is useful for electroless plating. ADVANTAGE - The method improves the durability of the product. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating the method for electroless plating (Drawing includes non-English language text).
