Abstract:
The outer-peripheral coating material of the present invention contains
a filler containing a laser-coloring powder containing at least one member selected from the group consisting of a metal and a metal compound each developing a color which differs from the original color when irradiated with a laser beam, and a ceramic powder composed of a ceramic other than the material which constitutes the laser-coloring powder, and
a dispersing medium,
wherein the filler contains the laser-coloring powder in an amount of 20 to 400 parts by mass relative to 100 parts by mass of the ceramic powder. An outer-peripheral coating layer formed with the outer-peripheral coating material of the present invention, when irradiated with a laser beam, develops a color in such a way that the metal or metal compound constituting the laser-coloring powder contained in the outer-peripheral coating layer produces a black color, and enables printing which is not deteriorated by chemical treatment, heat treatment, etc.
