Abstract
There is provided a process for forming a contained second layer over a first layer. The process comprises forming the first layer having a first surface energy and then treating the first layer with a photocurable surface-active composition which is a fluorinated ester or fluorinated imide of an α,β-unsaturated polyacid; exposing the photocurable surface-active composition patternwise with radiation resulting in exposed areas and unexposed areas; developing the photocurable surface-active composition to remove the unexposed areas resulting in a first layer having untreated portions in the unexposed areas and treated portions in the exposed areas, where the treated portions have a second surface energy that is lower than the first surface energy; and forming the second layer on the untreated portions of the first layer. There is also provided an organic electronic device made by the process.
