Abstract
PURPOSE: To obtain a semi-permanent drawing board of easy maintenance by forming an anodic oxidation film on the drawing surface and performing perfect hole sealing.
CONSTITUTION: The surface of an aluminum and aluminum alloy platelike body having undergone mechanical working or chemical working is cleaned. This platelike body is subjected to anodic oxidation treatment to form an anodic oxidation film on the surface. If necessary, it is subjected to coloring, dyeing and patterning to form the ground color of the drawing surface, after which it is subjected to perfect hole sealing. When the surface oxide film of a dark color system is formed or when it is colored to a dark color system, it is used as a blackboard. When it is formed with the oxide film of a bright color system or when it is colored to a bright color system, it is used as a while board. Chalk, water pens and oil pens are used for writing means. There are no particular limits for erasing methods, such as dry cloth, wet cloth. Thereby, the semipermanent drawing board of good drawing quality and easy maintenance is obtained.
