[PROBLEMS] To provide a photoimageable composition having high tent film strength, excellent adhesion, high sensitivity, and high resolution. SOLUTION: An acid group-containing polymer binder A and an ethylenically unsaturated compound B which can be developed in an aqueous alkali solution. And photoinitiator C, wherein A is 30 to 7 of the total amount of A and B. 0%, B is 30 to 70% of the total amount, C is 0.05 to 70% of the total amount A is MW 5000 to 40000, Tg4 Binder polymer A ′ and MW 410 at 0-100 ° C. A binder polymer A ″ having a Tg of 40 to 100 ° C., A ′ being 3 to 65% of the total amount, A ″ being 5 to 67% of the total amount, and B being an isocyanate compound B ′ and other ethylenically unsaturated In compound B ″, B ′ is the total amount of 2 -40%, B "is 0-28% of the total amount, 50% or more of the unsaturated groups of B 'and B" are methacrylate groups, C is triphenylphosphine and n-phenylglycine, Triphenylphosphine is 0.005 to 3% of the total amount, n -A photoimageable composition in which phenylglycine is 0.005 to 2% of the total amount. |
