To provide a positive active energy ray-sensitive dry film having excellent photosensitivity.
The positive active energy ray-sensitive dry film has a positive solid cellulose resin layer having sensitivity to active energy rays on the surface of a supporting material having no sensitivity to active energy rays. The resin layer is formed by applying a resin composition containing (A) at least one kind of unsaturated compound selected from vinylether group-containing compounds, vinylester group-containing compounds and propenylester group- containing compounds, (B) a cellulose resin having an acid functional group and (C) a photoacid generator as the essential components on the surface of the supporting material and then heating the applied layer to crosslink the composition.
