摘要

A process and an equipment for micro-pattern forming on the surface of a rolling roll (1), and a metallic thin sheet and preparation thereof by transfering the micro-pattern on the surface by use of the roll are provided. Such a rolling roll can be attained by a method wherein resin film (28) mixed with optical absorbing agent is formed on the surface, a Q switch YAG laser having an output of 5 to 100 W is applied to make a marking of this resin film, a part of the coated film is removed in strictly accordance with the pattern, then an etching process is applied to the roll surface. The metallic thin sheet skin pass rolled by this roll is used as a car panel being superior in pressworkability and sharpness of reflections.
