  • Publication number: 20140166613
    Abstract: The present invention relates to compositions which are particularly suitable for the etching and structuring of transparent, conductive antireflection coatings and of corresponding stacked layers, which are preferably present in touch-sensitive display screens or display elements. The latter are generally also known as touch-sensitive displays, touch panels or touch screens. In particular, these are compositions by means of which fine structures can be etched selectively into conductive transparent oxidic layers and into corresponding layer stacks.
