摘要: There is provided a hyper-branched polymer represented by the following formula (1) and having a weight-average molecular weight in a range of 1,000 to 1,000,000. In the formula (1), A1 is a group containing an aromatic ring, A2 is a group containing an amide group, A3 is a group containing sulfur, R0 is hydrogen or a substituted or unsubstituted hydrocarbon group having 1 to 10 carbon atoms, ml is in a range of 0.5 to 11, and n1 is in a range of 5 to 100.

摘要: A method for producing a plated part, includes: forming, on a surface of a base member, a catalyst activity inhibiting layer containing a polymer which has at least one of an amide group and an amino group; irradiating with light or heating a part of the surface of the base member on which the catalyst activity inhibiting layer is formed; applying an electroless plating catalyst to the surface of the base member heated or irradiated with the light; and bringing an electroless plating solution into contact with the surface of the base member to which the electroless plating catalyst is applied, to form an electroless plating film at a light-irradiated portion or a heated portion of the surface.
