Abstract

PURPOSE:To prevent decrease in reflectivity of a reflecting film and formation of pinholes of said film and to form the reflecting film so as to withstand use in environment at and under high temp. and high humidity by forming a protective material for the reflecting film having a larger tendency to ionization than the reflecting film on the reflecting film. CONSTITUTION:A reflecting film 2 for reflecting light is laminated on a transparent base body 11 according to the rugged surface thereof and a protective material 13 for the reflecting film is laminated thereon. A paint contg. a material having a higher tendency to ionization than the film 12, for example, a paint contg. zinc such as a coated film of zinc-rich paint or the like is used for the material 13. The above-mentioned zinc-rich paint refers to an epoxy resin or the like in which a large mat. of pouverous zinc powder is incorporated. A protective film 14 consisting of, for example, a resin coated film or the like is further laminated on the material 13. Then the zinc in the zinc-rich paint acts as a sacrifical anode to provide an effect of preventing electrolytic corrosion of the film 12 even if water or oxygen intrudes in the film 12 and the material 13.

FIG. 2 shows one embodiment of the present invention. That is, on a transparent substrate 11 made of, for example, transparent plastic, on which information is recorded on an uneven surface, a reflective film 12 made of, for example, aluminum is laminated according to the uneven surface. A reflective film protective material 13 is laminated on this reflective film 12.This reflective film protective material 13 has a reflective film of +17412 to prevent chemical changes in the reflective film 12.
Paints containing SA, which have a higher ionization tendency, are paints containing zinc, such as zinc-rich Indian coatings. In addition, the zinc-rich paint in the present invention contains a large amount of finely powdered zinc powder in a resin, and is, for example, one in which finely powdered zinc is contained in +fij resin such as epoxy resin or acrylic resin. A protective film 14 made of, for example, a resin coating is laminated on the reflective film protective material 13 to protect the reflective film and the information recording portion.
