PROBLEM TO BE SOLVED: To prevent slipping in a roll-type product and to prevent edge fusion by controlling the coefft. of sliding friction on the surface of a protective film not in contact with a photosensitive resin layer and by controlling the film thickness of the protective film to each specified range. ;SOLUTION: This photosensitive film consists of a supporting film, a photosensitive resin layer and a protective film. The coefft. of sliding friction (tan ) on the surface of the protective film not in contact with the photosensitive resin layer is controlled to 0.6 to 1.5, and the protective film is formed to 15 to 40 m thickness. The supporting film is preferably a polyethylene terephthalate film. As for the photosensitive resin to form the photosensitive resin layer, the resin containing a binder polymer, a photopolymn. initiator and a photopolymerizable vinyl compd. as the essential components can be used. As for the binder polymer, copolymers of alkylesters of (meth)acrylic acids or copolymers of alkylesters of (meth)acrylic acids and vinyl monomers which are copolymerizable with the esters can be used.;COPYRIGHT: (C)1998,JPO
