A stained sensitization resin comprising a binder resin, a photo-polymerization compound, a photo-polymerization inducer, a stained material and a solvent, is provided. The binder resin (A), which contains unsaturated function group, is made from the copolymerization of (A1)~(A3) and then reacts with (A4). The photo-polymerization inducer (C) is the at least one compound selected from the combination of triazine compound, acetophenone compound, biimidazole compound and oxime compound. (A1): a compound, which in one of its molecule contains at least one skeleton selected from the combination of the tricyclodecane skeleton and the dicyclopentadiene skeleton, and unsaturated bonds; (A2): compound, which contains the unsaturated bonds of (A1) and (A3) for polymerization; (A3): unsaturated carbonic acid; (A4): compound, which in one of its molecule contains the unsaturated bond and epoxy group.
