MARKING CARRIER IN FORM OF COMPOSITE LAMINAR HEAT-RESISTANT MATERIAL FOR LASER ABLATION Russian patent published in 2024 - IPC B23K26/18 G09F3/02 B32B33/00 

FIELD: production of composite materials.

SUBSTANCE: invention relates to composite laminar materials, namely to heat-resistant composite laminar materials used as marking carriers: labels, seals, labels, tags, etc., note here that marking bearing information on article to be marked is applied on marking carrier by laser ablation. Essence of the proposed invention consists in the fact that the marking carrier in the form of a composite laminar material for laser ablation comprises a bearing substrate and at least one information layer, the bearing substrate is made from a material with a maximum operating temperature of not less than 300 °C, and the information layers are made from an organosilicon polymer composition. Organosilicon polymer composition can be an organosilicon-based enamel paint, particularly based on polyorganosiloxane resin. Total constant thickness of information layers, excluding the thickness of alignment, can be not more than 100 mcm.

EFFECT: invention provides higher resistance of material to high temperatures, increased maximum operating temperature of application, heat resistance of material for laser ablation and wider range of its possible applications.
