(57) Abstract: [PROBLEMS] To provide a photocurable resin laminate that has good adhesion, followability and developability to a substrate and does not cause blocking of a cured resist in the production of a flexible wiring board. SOLUTION: (a) (i) α, β-unsaturated carboxylic acid, (ii) styrene derivative, and (iii) alkyl (meth) acrylate, hydroxyalkyl (meth) acrylate having a hydroxyalkyl group, etc. Supporting a vinyl copolymer obtained from the polymer, (b) a photopolymerizable unsaturated compound containing a copolymer of ethylene oxide and propylene oxide in the molecule, and (c) a photocurable resin layer containing a photopolymerizable initiator. The photocurable resin laminated body formed on the body is prepared. |
