ACRYLIC RESIN PRODUCT HAVING GOLD VAPOR DEPOSITION LAYER WITH PERSPECTIVE PROPERTY AND PREPARATION THEREOF

摘要

PURPOSE:To form a vapor deposition layer having both perspective property and conductivity in high close adhesiveness, by successively forming an SiO2-containing mixed vapor deposition layer, a vapor deposition layer comprising a specific metal and an Au vapor deposition layer to the surface of an acrylic resin product. CONSTITUTION:After a transparent acrylic resin product 1 is put in a vacuum tank and preheated, a vapor deposition layer 2 with a thickness of 30-100Angstrom consisting of an SiO2 single vapor deposition layer 21, an SiO2 and TiO2 mixed vapor deposition layer 22 and a TiO2 single vapor deposition layer 23 is at first formed. Succeedingly, a vapor deposition layer comprising one of Cu, Ti and Ag is formed thereon in a thickness of 10-30Angstrom and an Au vapor deposition layer 4 with a thickness of 30-200Angstrom is formed at last. By this method, a vapor deposition layer excellent in close adhesiveness to the acrylic resin product 1 and having both perspective property and conductivity can be formed.
