Abstract
To apply a photoimageable composition to a substrate, such as a printed circuit board, the photoimageable composition is dissolved in a solvent system which is a mixture of propylene glycol monomethylether and ethylene glycol butylether, acetate. The liquid solution is applied to the substrate. Then the photoimageable composition is dried to remove the solvent system and thereby produce a layer of the photoimageable composition on the substrate.
