Abstract
The invention provides an aqueous electrodeposition coating composition for a positive working resist and an image-forming method using the same. The coating composition is very stable under storage conditions and is capable of resulting in a positive working resist which is specifically useful in the preparation of a printed circuit board with mini-via-holes.
