Embodiment

[0107] In the following, the composition of the polymer layer is shown in more detail by way of example, without any restrictive effect:

[0108] Substrate Fraction (phr)

[0109] EB 284 85.1

[0110] HDDA 5.0

[0111] DVE 3 9.9

[0112] Carbon black 0.4

[0113] Titanium dioxide 63.2

[0114] Total 163.6

[0115] EB 284: Aliphatic, Difunctional Urethane Acrylates (Manufacturer: Cytec)

[0116] HDDA: Hexylene glycol diacrylate (manufacturer: BASF)

[0117] DVE 3: Divinyl ether (manufacturer: ISP or BASF)

[0118] Carbon black: Furnace black, particle size 56nm, surface area 45m 2 / g (Manufacturer: Evonik, Printex25)

[0119] TiO 2 : (Manufacturer: Kronos, Kronos 2160)

[0120] This composition was applied to form a layer with a thickness of 100 μm. Measurement samples of 30×50 mm were produced from the coating by punching.

Abstract

Pigment layer intended particularly for the permanent marking of glass, based on a polymer matrix which reacts predominantly with pulverization to a high-energy beam, more particularly to laser irradiation, comprising at least one titanium donor and a carbon donor which provides free carbon under energy irradiation.

Description

technical field [0001] The present invention relates to pigment layers intended for permanent marking of substrates, especially glass, and to methods for permanently scoring substrates, especially glass, by means of high-energy radiation. Background technique [0002] For the identification of components on vehicles, machinery, electronic and electrical equipment, or components consisting, for example, of glass, various technical labels are used, such as model identification plates, method control labels, guarantee marks and testing plaques ). Identification by means of laser labels and printed or coated metal nameplates has a growing place especially for high-value markings. Accordingly, information and advice for subsequent users is located on the various components. [0003] In addition to these methods, the information can also be obtained by inscribing directly on the article to be inscribed. Especially for the direct scoring and identification marking of metal or gl...
