ABSTRACT:
A method for the formation of a colored polymeric body which comprises subjecting a curable composition containing a color precursor and an onium salt to heat or actinic radiation to cure the composition, wherein the color precursor is converted to its colored form, and a curable composition capable of forming a colored polymeric body, are disclosed.
