Abstract
Novel epoxy acrylates and carboxyl group-containing epoxy acrylates of formulae II and III of the claims that are relatively highmolecular and are chemically crosslinkable can be used in photoresist formulations with the additional use of highly polymerized polymer binders. Such resist formulations are used in particular in the field of printed circuit boards and printing plates, are applicable from aqueous medium, are almost tack-free and have very good edge coverage, especially on conductors.
