Abstract
The present invention provides an indication appending method and an indication appended article that improve identifiability with ease. The indication appending method comprises the step of applying a coating material having a color different from a surface of the article onto the surface in the form of a layer, and the step of partially removing the coating material by irradiation with laser light and thereby forming identification information, which is a letter/character, a symbol, and/or a figure. The coating material may be applied onto a predetermined region, and thereby an indication may be formed by a part from which the coating material is removed.
Claims7
An indication appending method comprising:
- applying a first coating material, having a color which is different from that of a surface of an article, onto the surface of the article in the form of a layer;
- and
- partially removing the first coating material by irradiation with laser light and thereby forming an indication which is a letter/character, a symbol and/or a figure.
An indication appending method comprising:
- applying a first coating material onto a surface of an article in the form of a layer;
- applying a second coating material having a color which is different from that of the first coating material onto a surface of the first coating material in the form of a layer;
- and
- partially removing the second coating material while leaving the first coating material unremoved by irradiation with laser light and thereby forming an indication which is a letter/character, a symbol and/or a figure.
An indication appended article comprising:
- an indication, which is a letter/character, a symbol and/or a figure formed with a first coating material,
- wherein the first coating material is applied onto a surface of the article, partially removed by irradiation with laser light, and has a color different from that of the surface of the article.
An indication appended article comprising:
- a surface on which a first coating material is applied;
- and
- an indication on the surface, which is a letter/character, a symbol and/or a figure,
- wherein the indication is formed with a second coating material applied onto the first coating material, and partially removed by irradiation with laser light, and the second coating material has a color different from that of the first coating material.
