<P>PROBLEM TO BE SOLVED: To provide a multilayer film for plating capable of forming a metal film satisfactory in tight adhesion and superior in insulating reliability between patterns, a method of preparing metal film-coated material using the same, and a metal film-coated material. <P>SOLUTION: The multilayer film for plating is provided with a resin film and a plating receptive layer containing a polymer containing a function group and a polymerizable group forming mutual action with a plating catalyst or its precursor, or precursor thereof, wherein the plating receptive layer satisfies at least one of the following conditions 1-4. Condition 1: saturated water absorption ratio is 0.01-10 mass% in an environment of being a temperature of 25°C and an relative humidity of 50%; condition 2: saturated water absorption ratio is 0.05-20 mass% in an environment of being a temperature of 25°C and an relative humidity of 95%; condition 3: water absorption ratio after immersion in boiling water at 100°C for one hour is 0.1-30 mass%; condition 4: in an environment of being a temperature of 25°C and an relative humidity of 50%, surface contact angle after 5 μL of distilled water is dropped onto the plating receptive layer and allowed to stand for 15 sec is 50-150 degrees. <P>COPYRIGHT: (C)2010,JPO&INPIT |
