Estimating the term…
A photopolymerizable element comprising a layer of a photopolymerizable composition and a liquid developer-soluble or -dispersible transparent oriented film support laminated onto one surface of the photopolymerizable composition layer is advantageously employed for the production of a polymeric image without stripping of the film support. The element may further comprise a strippable protective film provided on the other surface of the photopolymerizable composition layer. The element of this invention is useful especially for the production of photoresists which are advantageously used for the manufacture of printed circuit boards.
A photopolymerizable element comprising a layer of a photopolymerizable composition and a transparent oriented film support laminated onto one surface of the photopolymerizable composition layer which support is soluble or dispersible in a liquid developer for the photopolymerizable composition layer and capable of transmitting actinic rays and which support is of a member selected from the group consisting of methyl methacrylate homopolymer and copolymers, vinyl chloride homopolymer and copolymers, polyvinyl alcohol, and mixtures thereof.
