2. Description of the Related Art Conventionally, as a method for forming characters, patterns, etc. by painting, it is general to use various printing methods such as screen printing, pad printing, hot stamping and offset printing on the painting. . These methods are methods for forming characters, patterns, etc. on the surface of the coating film.For example, when used for the exterior of a writing instrument, there is a problem with durability, and due to problems such as leveling of the printing surface, At present, the appearance characteristics such as texture are not satisfactory. Therefore, as a method for solving these problems, clear coating is applied again on the coating on which printing is formed to improve durability, texture and the like. On the other hand, as a pattern forming method other than the printing method, Japanese Patent Laid-Open No. 63-1756.
As described in No. 70, a liquid coating material containing a powder magnetic material is applied to an object to be coated, and a magnet is made to act while the coating film is still fluid, so that patterns such as patterns and letters are partially printed. A method of forming a cord has also been proposed. In this method, the magnetic material is oriented by the action of the magnet, and the pattern is generated by the reflection of light.
It is a method of expressing the information.
