(57) [Abstract] (with correction) [PROBLEMS] To provide good edge fusing property during storage and good followability during lamination to a substrate, good peelability, high resolution, Provided is a DFR for manufacturing an alkali-developed printed circuit board having characteristics such as high-speed developability. SOLUTION: (a) a resin for a binder, (b) a photopolymerizable unsaturated compound represented by the following formula (I): (R1-R4: H, CH 3; A, B: C2H4, C3H6; m1 + m2 + m3 + m4: 0-2 0; n1 + n2 + n3 + n4: 0-20) (c) a photopolymerizable unsaturated compound having two or more terminal ethylene groups, and (d) 2,4,5-triary-imidazolyl dimer A photopolymerizable resin composition is produced. |
