    摘要: A laser-marking laminated structure has at least a base layer (2), a masking layer (3) capable of being removed by irradiation with a laser beam, and an OP layer (4) formed in that order on a support element (1). The base layer and the masking layer are colored layers having colors distinctly different from each other in lightness. The laser-marking laminated structure is irradiated with a laser beam in a desired pattern including characters to remove portions of the masking layer (3) and the OP layer (4) corresponding to the pattern so that the pattern is displayed clearly on the laser-marking laminated structure because of the contrast between the color of the base layer (2) and that of the masking layer (4).

    摘要: A laser beam markable electric cable comprising an outer layer (13) enabling such marking to be performed, wherein said outer layer (13) is of a contrasting color relative to the color of an underlayer (14) which is absorbent at the laser beam wavelength. Said outer layer (13) is a thin layer which, during marking, is destroyed through its entire thickness by the laser beam (10) so as to reveal the underlayer (14).

    摘要: A system for creating marked can tabs may include an isolation mechanism located in the path of the tab material strip between a tab material dereeler and a tab forming press and a system suitable for marking the tab material strip. The isolation mechanism may be configured to convert discontinuous motion of the tab material strip proximate the tab forming press into continuous motion of the tab material strip at the dereeler. The system may be suitable for marking the tab material strip. The marking system may be located between the dereeler and the isolation mechanism such that the laser system acts on the tab material strip while it is moving at a relatively constant speed.

    摘要: A laser markable white pigment composition includes a first pigment which is markable by ultraviolet laser, a second pigment, which is nonabsorbing in the ultraviolet region of the optical spectrum and which has a white appearance in the visible region of the optical spectrum, with the ratio of the amount of first pigment to amount of second pigment being in the range of from 4:1 to 1:10, so that the second pigment is present in an amount sufficient to increase the optical density, that is the whitening effect, of the composition, without adversely affecting the laser markability of the composition, and a carrier which is at least one fluoropolymer transparent in the ultraviolet region of the optical spectrum.
