ABSTRACT:
This invention relates to dry processible photo polymers, a method for their production and uses thereof. The photo polymers are produced by selectively irradiating discrete zones of a precursor polymer by UV or visible light followed by thermal oxidation to create polymer films which have modified optical and surface relief properties. Such photo polymers can be used in a number of applications eg wave guiding.
