<p>Photocurable compositions which comprise a light sensitive composition in combination with at least one initiator therefor are improved by the use of dibenzoyl benzene as the photoinitiator. In a preferred combination, para-dibenzoyl benzene is employed in combination with para-di(4-dimethylaminobenzoyl) benzene. The photocurable compositions can be used for various purposes including preparation of lithographic printing plates.</p> |
