Abstract
PURPOSE: To improve uniformity, weather resistance and solidness of a light beam reflective layer by forming the light beam reflective layer of a metallic electroless layer constituting principally of nickel, etc.
CONSTITUTION: On one side of resin substrate 2, uneven surface 3 expressing reproduced information is provided and on this uneven surface 3, a reflective layer of a metallic electroless plating layer is bonded which consists principally of at least one kind of nickel, cobalt, tin and silver. In manufacture of this, an original plate where reproduced information is curved in an uneven shape is used to copy the unevenness on substrate 2 of vinyl-chloride-based resin. Next, uneven surface 3 is activated by hydrophilic processing and further, curving processing of palladium is performed at need. Then a light beam reflective layer of nickel containing several percents of phosphorus is formed by electroless metal plating and an urethane-based protective layer is formed on the reflection layer.
