Multilayer flexographic printing plate.

摘要

This invention provides a process for producing a multilayer, flexible photosensitive plate comprising (i) applying a first photosensitive elastomeric layer to a flexible substrate, (ii) curing the first photosensitive elastomeric layer by exposure to actinic radiation, and (iii) following this curing, applying a second layer, which is at least 0.2 mm thick, onto the first photosensitive layer, the second layer comprising a photosensitive elastomeric composition having no more than 1% by weight ethylenically unsaturated copolymerizable molecules with molecular weights less than 500. This multilayer photosensitive plate may be used as a flexographic printing plate if imagewise exposed and developed. These multilayer plates are particularly suitable for thermal development.
