A label is attached to a base material in a container. The container includes patterns formed in a plurality of stages on the base material by laser irradiation. The patterns may include an aggregation of dots formed by the laser irradiation. The container may further include a first information region and a second information region. Information including a numeral, a symbol, or an image is made visible by the patterns in the first information region. The second information region is formed on the label. Information including a numeral, a symbol, or an image is made visible in the second information region.

A composition for producing a laser-inscribable identification tag for attachment to an assembly to be identified includes: a polymeric plastic; and a filler. The filler comprises graphene particles, barium particles, and/or barium sulfate particles. In an embodiment, the polymeric plastic includes polypropylene, polyethylene, PVC, TPU, TPE, TPV, PP/PA, polyketone, PA, ABS, PET, and/or PMMA.

[PROBLEM] To provide a packaging and a display material which permit printing in distinct fashion by a laser, and which are of high transparency. [SOLUTION MEANS] A display material having at least one layer permitting printing as a result of laser irradiation, the display material being such that the printing occurs due to change in color caused by the laser irradiation in at least one region of said layer; when a digital microscope is used to carry out cross-sectional observation of said printed region and a nonprinted region, a significant difference in at least any one of RGB values indicating color elements is observed; and thickness of said printed region is not less than 5μm but not greater than 200 μm.

The present invention relates to laser-markable and laser-weldable polymeric materials which are distinguished by the fact that they comprise, as laser absorber, at least one copper-doped zinc sulfide.

Laser marked articles having a predetermined feature marked onto a wall that is either user readable, machine readable, or both. Also, methods of making the marked articles by laser marking.

A process of forming an identification marking within article formed from an at least partially optically transparent material for identification and validation, said process including the steps of (i) forming an indicia with an at least partially optically transparent material by way of subsurface laser engraving (SSLE); and (ii) forming a plurality of defects within or adjacent indicia within said at least partially optically transparent material resultant of the step of forming the indicia and from localized heating and irregularities in said at least partially optically transparent material, wherein said plurality of defects forms said identification marking

A system and method for performing laser marking may include identifying an event performed by a laser marking system. A laser marking unit may be driven to mark the feature on the part. The part may be illuminated with a visible illumination signal to indicate an occurrence of the event in response to identifying the event.

The present invention relates to a process for the laser treatment of effect pigment-containing coatings, to coatings produced using this process, and to the use thereof in decorative and security products.

Flame retardant thermoplastic compositions that are capable of being used in a laser direct structuring process. The compositions include a thermoplastic resin, a laser direct structuring additive, and a flame retardant. The compositions offer flame retardant characteristics while also substantially maintaining the mechanical properties of the base thermoplastic resin, such as the impact strength and/or HDT of the composition. The compositions can be used in a variety of applications such as personal computers, notebook and portable computers, cell phone and other such communications equipment.
