MULTILAYER PHOTOSENSITIVE STRUCTURE FOR FLEXOGRAPHY AND MANUFACTURING METHOD OF PLATE MATERIAL FOR FLEXOGRAPHY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a multilayer photosensitive structure for flexography which has high sensitivity and high resolution to infrared laser light and a simple layer structure and can be made into a plate directly and a manufactur ing method of a plate material for flexography using the same.;SOLUTION: The multilayer photosensitive structure for flexography has a substrate layer (A), a photosensitive resin layer (B) located on the layer (A) and containing an elastomeric binder, a monomer of one kind or more and an initiator sensitive to a noninfrared radiation and a mask forming layer (C) located on the layer (B) and containing a binder having coat-forming power and a color developer being transparent substantially to the noninfrared radiation, made to develop color by the light in an infrared region or heat and forming a colored part intercepting the noninfrared radiation.;COPYRIGHT: (C)2001,JPO
