PURPOSE:To improve the adhesive property against a metal surface by incorporating to the titled composition, the compd. which is composed of a specific beta-diketone or its derivative shown by the formula and has >=70 deg.C b.p. CONSTITUTION:The titled composition is prepared by incorporating the beta- diketone or its derivative shown by the formula wherein R1 and R2 are each an alkyl, a phenyl, a substd. phenyl, a halogenated alkyl, an aryl or a teryl group, and having >=70 deg.C b.p. to the photosensitive resin comprising an ethylenically unsaturated compd., a binder polymer, a polymerization initiator. The additional amount of the beta-diketone or its derivative shown by the formula is 0.01-5wt%, preferably, 0.05-2wt% on the weight basis of the titled composition. |
