Abstract
A structure comprising a layer of polymeric material containing epoxy groups having preselected regions of different degrees of polymerization and different refractive indices; and a method for forming a structure comprising a layer of polymeric material containing epoxy groups having preselected regions of differing degrees of polymerization and differing refractive indices which comprises providing a polymeric material containing epoxy groups on a support and selectively modifying the refractive index in said material.
