Abstract
A process for the manufacture of a scattering polymer film can include (a) making available a film made of organic polymer, (b) applying, to one of the faces of the said film, a liquid composition (c) heating and/or irradiating the layer of liquid composition to form a cured scattering layer. A scattering polymer film can be obtained by this process. A substrate for OLED can include such a film adhesively bonded to a transparent substrate.
