Abstract: PURPOSE:To provide a method which is good for mass production and of good workability and can form a superior magnetic pattern by applying a magnetic coating material to a material to be coated forming a film for magnetization, dot magnetizing the film for magnetization and then applying a magnetic pattern-forming coating material to form a magnetic pattern formed film. CONSTITUTION:When a pattern film is formed, first a magnetic coating material containing permanently magnetizable particle powder is applied onto a material 11 to be coated, and a magnetization film 12 having the leaking magnetic flux density of 1-100 Gauss is formed. Then the film for magnetization thus formed is dot magnetized by using a single-pole or a multipole magnetizing tool, for example, a magnetizing pole 23 and applying power from a magnetizing power source device 14 to the pole. Successively magnetic induction particle powder having saturated magnetization of 5-100emu/g and, if required, a magnetic pattern forming coating material containing a coloring pigment and/or a bright pigment is applied to form a magnetic pattern formed film. A magnetic pattern which is good for mass production of good workability, bright and of high design properties without being affected by the material to be coated is formed.
