ABSTRACT:
Diepoxides which may be photopolymerized in the presence or absence of a photosensitizer contain a group having conjugated unsaturation attached to a nitrogen heterocycle, such as a hydantoin or barbituric acid residue, forming part of an advanced diepoxide. The resultant photopolymer may be crosslinked by heating in the presence of a curing agent for epoxide resins.
The diepoxides are of use in the production of printing plates and printed circuits, especially multilayer printed circuits.
