This paper size applies to Chinese National Standards (CNS) A4 *! ^ (210X 297 mm) 19 In the Ministry of Economic Affairs, the Ministry of Industry and Commerce exempts the cooperatives to gather 38700 ^ A7 ____ 广 B7______ 5. Description of the invention (π) 〇: When the sputtered film or metal film is completely peeled off from the polycarbonate plate (substrate) * 泮 With the destruction of the substrate • or the polycarbonate plate is broken • △: The sputtered film or metal film is made of polycarbonate The part of the board is falling, and the peeling surface is cracked or polycarbonate! The peeling surface of the ester plate is wrinkled and cracked. X: The sputtered film or gold film is left on the polycarbonate plate or is polymerized with each other. Carbonate plate peels off easily. It is proved from Table 1 that the composition of Examples 1 to 5 has better adhesion than the adhesives of Comparative Examples 1 to 4. It represents a synthetic single-sided reading method for adhesive discs that represents the information recording layer of DVD. The resin substrate (3), metal sputter-treated substrate (2), and translucent film-treated substrate (1) which can be used as polycarbonate are extremely suitable UV-curable adhesives for adhering to each other. The hardening type adhesive composition is provided on a composite disc such as a D VD, and is provided with gold, silver, and silicone. Materials such as translucent film-treated substrates (1), metal substrates (2), resin substrates (3), such as polycarbonate, are cured by ultraviolet rays when they are adhered to each other. The properties can fully balance the three substrates (1) to (3) above to maintain complete adhesive strength. Adhesives are made by bonding optical discs, especially translucent film-treated substrates and metal sputter-treated substrates. Bonding DVD — ROM is extremely useful from the standpoint of adhesiveness, protection, and productivity. This paper size applies to China National Standard (CNS) A4 specification (210X297).
