Water soluble photosensitive resin composition and film using same

A film comprising:

• at least one release film;
• and
• a resin layer, at least one surface of the resin layer is attached to a surface of the at least one release film, the resin layer is formed by a water soluble photosensitive resin composition, the water soluble photosensitive resin composition comprising:
• a polymer containing oxazolinyl;
• a photosensitive monomer;
• and
• a photo-initiator;
• wherein each of the polymer containing oxazolinyl, the photosensitive monomer, and the photo-initiator is water soluble or water dispersible, both of the polymer containing oxazolinyl and the photosensitive monomer have a plurality of carbon-carbon double bonds, the photosensitive monomer comprises a plurality of ethoxy groups, the polymer containing oxazolinyl and the photosensitive monomer polymerize to form a dense cross-linking network structure when the water soluble photosensitive resin composition is exposed to ultraviolet radiation.
