A new method capable of forming a circuit by performing metal plating on a desired portion on a substrate through a small number of steps regardless of the kind of the substrate. A method for forming a circuit on a substrate characterized in that when forming a circuit by plating on a substrate, the method includes steps of applying a coating film containing a silicone oligomer and a catalyst metal onto the substrate, and thereafter, performing an activation treatment of the catalyst metal in the coating film to make the catalyst metal exhibit autocatalytic properties, and then, performing electroless plating.

Method for forming circuit on substrate

An object of the present invention is to provide a silicon oligomer having a novel function that has not been achieved by a conventional condensation product of water and a tetraalkoxysilane. Provided are a silicon oligomer represented by the following formula (I) and a production method therefor:  

Silicon oligomer and production method therefor

An object is to provide a technique capable of forming a film having a dark black appearance and high corrosion resistance on a zinc plated component in a simple process, and a black coating film-forming vehicle component and/or fastening component that is obtained by: treating a surface of a zinc plated metal substrate with a black chemical conversion treatment agent containing trivalent chromium as an active ingredient, to form a black chemical conversion treatment film having an L value (brightness) of from 33 to 30; coating a black coating composition containing a black pigment in an amount of from 25 to 65% by weight in a thermosetting film-forming component and an alkoxysilane oligomer, on the black chemical conversion treatment film; and heat-curing the black coating composition thus coated.

Black coating film-forming vehicle component and/or fastening component, and manufacturing method thereof
