This method for manufacturing a laminate having the abovementioned properties includes: (1) using active energy rays to cure, on an organic resin substrate, an acrylic silicone resin composition having an inorganic component percentage X of 0.2 to 0.8 to form an intermediate layer, (2) dry-etching the surface of the intermediate layer obtained at step (1) using a non-oxidizing gas plasma of a plasma irradiation amount Y correlated with the inorganic component percentage X; and (3) plasma-polymerizing an organosilicon compound to form a hard coat layer on the surface of the intermediate layer obtained at step (2).

A plasma treatment method is provided. The method includes generating a planar plasma in a plasma treatment chamber, observing an effective influence region of the planar plasma by using an optical observation system in which an observation lens has a transparent substrate and a fluorescent coating thereon, adjusting a location of the observation lens to observe a brightness change of the fluorescent coating and the transparent substrate to obtain a location and a thickness range of the effective influence region of the planar plasma, and then adjusting a location of the observation lens to observe a brightness change of the fluorescent coating and the transparent substrate to obtain a location and a thickness range of the effective influence region of the planar plasma. A location of a sample is adjusted to within the effective influence region, and a plasma treatment is then performed on the sample.

A metering valve comprises a closable media passage leading from a media supply to a nozzle opening, wherein the medium can be applied to the workpiece in a metered manner through the nozzle opening. The metering valve is provided with a plasma generator by which the workpiece can be acted on by a plasma jet.

The present disclosure relates to coated non-metallic substrates and coated metallic substrates and methods for producing such coated substrates. A variant of the method is characterized in that a mat or glossy coating is underneath a metallic layer obtained in some eases by way of vapor deposition and/or sputtering. In another variant, the metallic layer is sufficiently thin so that it remains transparent or translucent to visible light. The coated substrates may include multiple layers such as metallic layers, polysiloxane layers, a color layer, a conversion layer, a primer layer, and/or a transparent or colored layer. An application system for applying a metallic layer to at least one surface of a substrate may include a plasma generator and/or a corona system for treating one or more layers by plasma treatment and/or corona treatment.
