ABSTRACT:
A liquid composition for application as a coating to screens of video display terminals (VDT's). The composition comprises a mixture of pure silica as a flattening agent, a surface active copolymer to minimize the build-up of static electricity on the surface of the screen, hydroxyethyl cellulose polymer as a thickener and glycerol as a carrier. The ingredients are present in relative concentrations so as to be effective for their intended purpose in the final mixture. The composition according to the present invention when applied as a coating to a VDT screen results in dispersion or defraction of light in a very effective manner, while at that same time reducing static electricity on the screen and cleaning the screen.
