Process for preparing printed-circuit board

摘要

A process for preparing a printed circuit board. The process involves successive steps of coating a photosensitive electrodeposition coating composition onto a printed-circuit copper-clad, laminated base plate to form a photosensitive resist film, applying a pattern mask onto the photosensitive resist film, exposing to an active light, developing and etching. Also the printed-circuit copper-clad, laminated base plate is subjected to a corrosion preventing treatment after cladding or laminating and prior to the step of coating the electrodeposition coating composition thereonto with a nitrogen-containing heterocyclic compound as a corrosion inhibitor.
