    摘要: A process for coating a substrate with an essentially colorless radiation curable composition which comprises coating said substrate with a visible light sensitive composition comprising a free radical addition polymerizable or crosslinkable material and a photobleachable ionic dye-counter ion compound capable of absorbing visible light and generating free radicals; exposing said composition to light to harden said composition; and bleaching said composition to an essentially colorless state, and photohardenable compositions containing photobleachable ionic dye-counter ion compounds as photoinitiators useful in the aforesaid process.
