Abstract

The present invention is an invention providing a photographic emulsion surface protective layer transfer sheet, characterized by having on one surface of a releasable support a photographic emulsion surface protective layer which is adhesive and in an uncured state, and characterized in that the photographic emulsion surface protective layer in an uncured state comprises an ionized radiation-curable resin composition containing a hydrophilic group-containing monofunctional (meth)acrylate and a polyfunctional (meth)acrylate. This transfer sheet can have an adhesive layer excellent in scratch resistance, close adhesion to an emulsion surface and solvent resistance. Therefore, when this transfer sheet is used particularly for forming a protective layer on the emulsion surface of a photomask, the photomask capable of long-term consistent use is obtained.
