To provide a functional support having highly sensitive photoreactivity in visible light region, to provide a graft polymer layer laminate provided with a graft pattern layer which is formed by using the functional support, has high sensitivity and has suppressed decrease in film thickness over time even after heating storage, to provide a metal ion-containing material obtained by using the graft polymer layer laminate, and to provide a metal film laminate.
The functional support is prepared by binding an oxime ester compound which has an initiation part having photopolymerization initiation ability and a binding part with the support onto the support via the binding part. The graft polymer layer laminate having a graft polymer layer directly bound with the surface of the support can be obtained by bringing a composition including a compound having polymerizable groups into contact with the surface of the functional support and, thereafter, applying energy to the surface of the functional support.
