Abstract: Disclosed is a method for inscribing or marking surfaces (1), especially metal surfaces. In said method, the surface (1) that is to be inscribed or marked is coated with an absorption promoter (2) in a first step, whereupon a high-energy beam (4), e.g. a laser beam, which colors the surface (1) as a result of the interaction with the absorption promoter by means of a temperature increase, is applied to surface elements that re to be inscribed or colored.

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.

Abstract: A process for preparing titanium carbide using a pigment formulation having at least one titanium compound and a carbon compound and/or elemental carbon, the pigment formulation reacting under laser irradiation to form TiC.

Abstract: The invention relates to a label with antiforgery security, comprising an adhesive layer applied to a lower face of a support layer. In or on the bare face of the adhesive layer, a plurality of inclusions are present which contain at least one reversibly detective additive. When the label is bonded to a base, the inclusions are forced into the adhesive layer such that layers of the label above the inclusions are deformed, thereby forming haptically distinguishable and optically visible bumps in a surface of an upper support layer.

Abstract: A multilayer laser transfer film for permanently inscribing parts made from at least one backing layer, where on at least part of the underside of the backing layer there is a first adhesion layer, characterized in that, on the backing-layer side of the laser transfer film, this being the location of the first adhesion layer, there are at least two pigment layers, preferably a first pigment layer applied to at least part of the material and comprising at least one glass flux pigment, and a second pigment layer applied to at least part of the material and comprising at least one laser-sensitive pigment.

Abstract: The invention relates to a multi-layer laser transfer film for the permanent labeling of components, comprising at least one support layer, whereby a first adhesive layer is at least partly provided on the underside of the support layer, characterised in that on the side of the support layer for the laser transfer film on which the first adhesive layer is provided, at least two pigment layers containing a laser-sensitive pigment are at least partly provided, whereby the concentration of the laser-sensitive pigment in the pigment layers varies.

Abstract: Laser transfer film for durable inscription on components made from at least one backing layer, where on at least part of the underside of the backing layer there is an adhesion layer, wherein a pigment layer which comprises at least one laser-sensitive pigment has been applied to at least part of the adhesion layer and/or backing layer.

Abstract: A label for concealing information, comprising at least
