A transmissive display pattern forming method of a light-transmissive injection molded product having a vacuum metallized layer is provided to reduce the process and the cost and to shorten the manufacturing time by laser-processing transmissive display patterns without adding a shielding layer, by adding a shielding laser reactant to a base layer. A method for forming transmissive display patterns(30) on the surface of a light-transmissive injection molded product(1) having a vacuum metallized layer(13) comprises the steps of: cleaning the injection molded product having a light-transmissive surface(S01); forming a base layer(11) containing a shielding laser reactant, on the surface of the injection molded product(S02); forming the vacuum metallized layer on the upside of the base layer(S03); laser-processing transmissive display patterns on the vacuum metallized layer and the base layer(S04); and forming a light-transmissive protection layer(15) on the upside of the vacuum metallized layer(S05). |
