Abstract
A method of forming an image having multiple phases is disclosed herein. The method includes forming exposed and unexposed areas, the exposed areas comprising a first polymer network exhibiting first and second phases that are chemically connected and have different refractive indices, the first phase being continuous, and the second phase comprising a plurality of structures dispersed within the first phase, and the unexposed areas comprising a second polymer network comprising third and fourth phases that are chemically connected and have different refractive indices, the third phase being continuous, and the fourth phase comprising a plurality of structures dispersed within the third phase. The first and second polymer networks are chemically connected, and morphology formed by the first and second phases is different than that formed by the third and fourth phases.
