Abstract
PURPOSE: To give marking to an opaque substance by providing two contacting substances one of which is transparent and the other opaque that has a higher melting point than the transparent substance, and by irradiating a laser lay on the opaque substance.
CONSTITUTION: A laser lay 5 from a laser unit 1 is collected by a lense 2 and irradiated on a point 41 of a laminate consisting of a transparent substance 3 and an opaque substance 4. The opaque substance that has absorbed the laser lay at the point 41, is scattered as high temperature particles 6. The particles hit the surface of the transparent substance 3 and produce a scratch 31, thus giving a required marking. In order to produce the above mentioned scratch 31, temperature of the scattered particles 6 must be higher than the melting point of the transparent substance 3. This requirement is, more or less, fulfilled when the opaque substance 4 has a higher melting point than the transparent substance 3 has.
