ABSTRACT:
A presensitized light sensitive sheet structure suitable for producing a dry transfer element, comprising a transparent substrate having a release coating thereon, and overlying the release coating a photo-sensitive layer comprising a conventional photopolymerizable compound, an initiator therefor, and a binder. After light exposure to an original through the transparent substrate and development to remove unexposed portions, the remaining image portions have a greater adhesion for a receptor surface when applied thereto under pressure than the adhesion of the indicia to the transparent substrate under like pressure.
