Multilayered photosensitive material for flexographic printing plate |
摘要 |
<p>A multilayered photosensitive material for processing into a flexographic printing plate by direct patterning with an infrared laser beam comprises: (A) a substrate; (B) a photosensitive resinous layer having sensitivity to light except infrared light and comprising (b1) an elastomeric binder resin, (b2) a polymerizable monomeric compound and (b3) a polymerization initiator formed on the substrate (A) ; (C) a barrier layer of a composition comprising a resin such as a polyvinyl pyrrolidone and alkali-soluble cellulose compounds, which transmits light other than infrared light and is removable in the development treatment, formed on the photosensitive resinous layer (B); and (D) a masking layer of a composition comprising (d1) a film-forming binder resin, (d2) an infrared absorbing compound and (d3) a compound having no transmissivity to light other than infrared light and removable by irradiation with an infrared laser beam, formed on the barrier layer (C).</p> |
