Abstract
A light control film is described comprising a light input surface and alight output surface opposite the light input surface; alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface, wherein the absorptive regions comprise light-absorbing or light-reflecting particles and a dried aqueous dispersion of an organic polymer. The light control film can have improved on-axis transmission in combination with sufficiently high sheet resistance such that the film does not detract from the responsiveness of a touch screen of an electronic device. Also described is a coated article and method of making.
