    • A pattern is formed by applying a coating composition containing magnetic particles to an article so that a coating film is formed, and a plurality of sheet form magnets are placed along the front surface of this coating film. Adjacent sheet form magnets are arranged in such a state that the magnetic poles on the front surface and the magnetic poles on the back surface are different between adjacent sheet form magnets, and side surfaces of the sheet form magnets contact each other. The coating composition contains a thermoplastic resin, magnetic particles with flaky form and a specific low boiling point solvent and a specific high boiling point solvent. A magnetic field is applied to the coating film by the sheet form magnets, so that the magnetic particles in the coating film are oriented by the magnetic field and the magnetic particles are oriented substantially parallel to the front surface of the coating film above the contact portions between the sheet form magnets. Light is reflected from the magnetic particles in the coating film so that a pattern is formed.
    • 通过将含有磁性颗粒的涂料组合物涂布到制品上形成涂膜,沿着该涂膜的前表面放置多个片状磁体,形成图案。 相邻的片状磁体以相邻的片状磁体之间的前表面上的磁极和背面的磁极与磁极之间不同的状态配置,片状磁体的侧面彼此接触。 涂料组合物含有热塑性树脂,片状磁性颗粒和特定的低沸点溶剂和特定的高沸点溶剂。 通过片状磁体对涂膜施加磁场,使得涂膜中的磁性颗粒通过磁场取向,并且磁性颗粒基本平行于涂层膜的接触部分上方的前表面 在片状磁体之间。 光从涂膜中的磁性颗粒反射,形成图案。
