PHOTOPOLYMER PRINTING PLATE PRECURSOR. |
摘要 |
A photopolymer printing plate precursor comprising a photosensitive coating on a support, wherein said photosensitive coating comprises a composition that is photopolymerizable upon absorption of light, said composition comprising at least one binder, a polymerizable compound, a sensitizer and a photoinitiator, characterized in that said binder is a copolymer that has a Tg of less than 70 °C, and wherein 1 to 50 mol-% of the monomeric units of said copolymer are substituted by at least one acidic group, has a very high sensitivity and resistence of the exposed image parts against alkaline developers, when exposed with a laser, even if no pre-heat step is performed. |
