PURPOSE:To develop an image having a three-dimensional feeling by a method wherein planar hematite particles of specific average diameter, thickness, and planar ratio are compounded and kneaded in a rubber or resin composition forming base, a magnetic field is applied to the kneaded material in a fluid state, and the kneaded material is cured to be a rubber or resin molded article. CONSTITUTION:Planar hematite particles of 0.5-5.0mum average diameter, 50-500Angstrom thickness, and 50:1-500:1 planar ratio are compounded and kneaded in a rubber or resin composition forming base. When a magnetic field is applied to the kneaded material in a fluid state and the kneaded material is cured to be a rubber or resin molded article, an image formed by controlling the strength and direction of a magnetic flux can be developed on the rubber or resin molded article, and the image developed part is seen as if it is recessed. The large color difference between a magnetic field applied part and the other part results in a remarkably good three- dimensional feeling. Because the planar hematite particle has a luster of gold, it becomes a golden glossy rubber or resin having a metallic luster by being compounded in the rubber or resin composition forming base. Therefore, a high-quality feeling and a massive feeling are further improved in addition to the forming of an image with a three-dimensional feeling. |
