Problems solved by technology

However, with this method, since 18 to 72 hours of heating etching is required, there is a possibility of damaging the emulsion surface, and in the coating process (undried coating process), it is difficult to control the film thickness, which is difficult for practical use.

Embodiment 1

[0056] ① Preparation of support

[0057] On the surface of a polyethylene terephthalate (hereinafter referred to as PET) film with a thickness of 50 μm stretched biaxially, the following peeling layer forming liquid is coated with a roll coater, and dried for 1 minute at 130° C. Thus, a peeling layer having a thickness of 2 μm was formed.

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.

Description

technical field [0001] The present invention relates to a transfer film used for transferring a protective layer to a photomask used for pattern formation of a printed circuit board or a display panel, and to an emulsion surface of a photomask for plate making, and to protecting the emulsion surface by the protective layer photomask. Background technique [0002] The surface protection methods of various materials are known so far. There is a method of attaching a protective layer provided with an adhesive layer on the surface of a film such as a polyester film to the surface of an object, and a protective layer is provided on a peelable film. layer, through adhesives or adhesives, the method of transferring the protective layer to the surface of the object, etc. When the protective layer is transferred to the surface of the object by such an adhesive or adhesive, although there is an advantage that a thin protective layer can be provided, the strength of the adhesive layer...
