Multilayer film for plating, method of manufacturing metal film-coated material and metal film-coated material

A multilayer film for plating comprising, on a surface of a first substrate, a plating receptive layer which contains a polymer having a polymerizable group and an alkylcyano group, or which contains a polymer precursor capable of forming a polymer having a polymerizable group and an alkylcyano group,

• wherein the plating receptive layer on the first substrate is transferable to a second substrate to form the plating receptive layer on the second substrate, and the plating receptive layer satisfies at least one selected from the group consisting of the following (1)-(4):
• (1) the saturated water absorption ratio of the plating receptive layer is from 0.01% by mass to 10% by mass in an environment of a temperature of 25° C. and relative humidity of 50%;
• (2) the saturated water absorption ratio of the plating receptive layer is from 0.05% by mass to 20% by mass in an environment of a temperature of 25° C. and relative humidity of 95%;
• (3) the water absorption ratio of the plating receptive layer is from 0.1% by mass to 30% by mass after immersion of the plating receptive layer in boiling water at 100° C. for one hour;
• and
• (4) the surface contact angle of distilled water is from 50° to 150° after 5 μl of the distilled water is dropped onto the plating receptive layer and allowed to stand for 15 seconds in an environment of a temperature of 25° C. and relative humidity of 50%.
