<p>A composition is disclosed which is photopolymerizable upon absorption of light in the wavelength range between 300 and 450 nm, the composition comprising a binder, a polymerizable compound, a sensitizer and a photoinitiator, characterized in that the sensitizer is an optical brightening agent. A high speed is obtained, enabling the preparation of a lithographic photopolymer plates with low-cost blue or violet laser diodes.</p> |
