PROBLEM TO BE SOLVED: To provide a coating material for an optical film which can be easily shaped, which has excellent productivity and a wide range for selecting a refractive index, which can be uniformly applied even on the surface of a substance having low surface tension, to provide an optical multilayered film formed by using the coating material, and to provide a reflective screen having the optical multilayer film. SOLUTION: The coating material for an optical film contains pigment fine particles, an organic solvent, a binder which induces hardening reaction by absorbing energy, a dispersant having a lipophilic group and a hydrophilic group, and a fluorine-based surfactant having a perfluoro group and a hydrophilic group, in which the hydrophilic group of the dispersant and the hydrophilic group of the fluorine-based surfactant comprise atomic groups having a common element and an oxygen atom.
