Plastic articles suitable for electroless plating

A plastic article for electroless plating in which a semi-cured or cured product of a curable resin composition comprises:

• (a) at least one cyanate ester compound selected from the group consisting of
• (1) a polyfunctional cyanate ester monomer,
• (2) a homoprepolymer of one or more cyanate esters of (1), and
• (3) a coprepolymer of (1) and an amine,
• (b) at least one diene-type rubber, and
• (c) at least one maleimide compound selected from the group consisting of:
• (1) a polyfunctional maleimide,
• (2) a homoprepolymer of one or more maleimides of (1), and
• (3) a coprepolymer of (1) and an amine,
• said composition including a mixture of components (a), (b) and (c), a preliminary reaction product of components (a), (b) and (c), the combination of said mixture and said preliminary reaction product, the combination of (a) and the preliminary reaction product of (b) and (c), the combination of (b) and the preliminary reaction product of (a) and (c), or the combination of (c) and the preliminary reaction product of (a) and (b), is formed on a plastic substrate.
