PURPOSE:To obtain the synthetic resin composite capable of suppressing and preventing the deterioration of an aluminum film even under severe use environment of high temp. and humidity in which brine is further participitated by forming an aluminum film on the surface of a molded product made of a transparent synthetic resin and using a film having hydrophobicity thereon. CONSTITUTION:The aluminum film provided on a molded product made of a transparent synthetic resin has the min. thickness having reflectivity usable as a reflecting mirror or a decorative article and may be set to a thickness range not damaging the close adhesiveness to a substrate and not generating inferior appearance such as the generation of a crack in the film but the most pref. thickness thereof is 500 - 1,000Angstrom . A hydrophobic film contains a high-molecular substance low in water absorbability and water permeability as a film forming element and this element means a soft resin such as polybutadiene, a styrene/polybutadiene copolymer or the like and the most pref. resin is polybutadiene. By this method, a composite excellent in corrosion resistance not generating the deterioration of the aluminum film even under severe use environment of high temp. and humidity in which brine is further participitated can be prepared. |
