Method for improving the adhesion of a photopolymerizable composition to copper

A method of increasing the adhesion of a photopolymerizable composition and the photopolymerized composition formed therefrom, which method comprises the step of adding an adhesion promoter, which consists essentially of a polycarboxylic acid having three to six carbon atoms, to the photopolymerizab...
