Title:
PHOTOCURABLE COMPOSITIONS AND FLEXOGRAPHIC PRINTING PLATES COMPRISING THE SAME
Document Type and Number:
WIPO Patent Application WO/2005/109101
Kind Code:
A1
Abstract:
The present invention relates to photocurable compositions for use in flexographic printing plates comprising selectively hydrogenated block copolymers of conjugated dienes and monoalkenyl arenes and flexographic printing plates made from the same. The block copolymers, either linear or radial, have terminal blocks of unsaturated conjugated diene. The block copolymer is further comprised of monoalkenyl arene blocks and hydrogenated conjugated diene blocks. The compositions exhibit exceptional improvement in degree of cure over comparative selectively hydrogenated block copolymers.
