Process of producing diffraction gratings on the surfaces of articles |
摘要 |
A process of producing an article having a surface provided with an optical diffraction grating such that the surface generates visible color when illuminated with diffuse white light. The process involves deforming a starting material to produce the article having the surface and, during the deforming step, impressing a diffraction relief pattern on the surface by a tool provided with a bearing surface having a corresponding surface relief pattern of parallel lines that contacts the surface of the article under pressure. While the diffraction relief patter is being impressed, the surface is caused to slide in a direction of movement relative to the bearing surface of the tool. The invention also relates to the article. |
