PURPOSE: A photosensitive composition, a photosensitivity film, a photosensitive laminated structure, a persistent pattern formation method, and a print board are provided to secure the high-sensitivity, and to perform a negative patternmaking. CONSTITUTION: A photosensitive composition includes a binder, a polymerizable compound, a photopolymerization initiator, a chain transfer agent, and a heat cross-linker. The chain transfer agent is marked with chemical formula A. In the chemical formula A, R1 and R2 are a hydrogen atom or an organic functional group. Y is either an oxygen atom or a sulfur atom. Z is an organic linking chain with n organic functions.
