摘要

The emulsion (18) has a plastic globule comprising a center particle size of 6 to 15 micrometers, and a transparent paint produced with single component paint or two component paints on water base. The plastic globule is made of polymethyl methacrylate. The plastic globule has a weight of 38 percent to 48 percent of the emulsion. A contrast particle such as flame soot is added to the emulsion with a weight percentage of 0.05 to 0.5, where the emulsion is sprayed on a front side and a side facing a user, of a screen surface (16) of a projection screen (10). An independent claim is also included for a multi-touch screen comprising a screen layer.
