LAMINATE AND METHOD FOR MANUFACTURING CONDUCTIVE SUBSTRATE

To provide a laminate having excellent storage stability.SOLUTION: There is provided a laminate having, in this order, a substrate, an underlying layer, and a plating layer precursor layer disposed in contact with the underlying layer, in which the underlying layer has a thickness of 1 to 20 μm, contains an oxime ester-based polymerization initiator, and the plating layer precursor layer contains an oxime ester-based polymer of the same type as the oxime ester-based polymerization initiator contained in the underlying layer, a polymer having a dissociative functional group, and a polymerizable compound that is a compound different from the polymer, a content of the oxime ester-based polymerization initiator in the underlying layer is higher than a content of the oxime ester-based polymerization initiator in the plating layer precursor layer, and the laminate satisfies a predetermined requirement.SELECTED DRAWING: None 【課題】 保存安定性に優れる積層体を提供すること。【解決手段】 基板と、下地層と、上記下地層と接触して配置された被めっき層前駆体層とをこの順に有する積層体であって、上記下地層の厚みが１～２０μｍであり、上記下地層が、オキシムエステル系重合開始剤を含み、上記被めっき層前駆体層が、上記下地層に含まれる上記オキシムエステル系重合開始剤と同種のオキシムエステル系重合体、解離性官能基を有するポリマー、および、上記ポリマーとは異なる化合物である重合性化合物を含み、上記下地層中における上記オキシムエステル系重合開始剤の含有量が、上記被めっき層前駆体層中における上記オキシムエステル系重合開始剤の含有量よりも多く、所定の要件を満たす、積層体。【選択図】なし
