PHOTOIMAGEABLE COMPOSITION HAVING AN ACRYLIC-FUNCTIONAL UV STABILIZER

摘要

A negative-acting photoimageable composition including a photopolymerizable compound(c), a binder polymer and a free-radical generating chemical system is improved by the inclusion of an acrylic functional U.V. stabilizer either incorporated in the binder polymer and/or as a portion of the photopolymerizable compounds and the use of phenyl acridine as at least a portion of the free-radical generating chemical system.
