Method for producing antiglare film

A method for producing an antiglare film, comprising:

• a coating liquid preparation step of preparing an antiglare layer-forming coating liquid in which at least two resin materials incompatible with each other are dissolved in at least one solvent, and a low-refractive index layer-forming coating liquid in which a first polymer whose substituent contains a molecular structure to decrease a refractive index of whole polymer and one or more resin materials which form a phase-separation structure with the first polymer are dissolved in at least one solvent;
• a coating step of applying the low-refractive index layer-forming coating liquid as an upper layer and the antiglare layer-forming coating liquid as a lower layer on a support to form a coating layer;
• and
• a drying step of drying the coating layer making the low-refractive index layer-forming coating liquid and the antiglare layer-forming coating liquid cause phase-separation so as to form a low-refractive index layer and an antiglare layer,
• wherein a ratio of the first polymer and the one or more resin materials to the at least one solvent in the low-refractive index layer-forming coating liquid, and a ratio of the at least two resin materials to the at least one solvent in the antiglare layer-forming coating liquid are adjusted in the coating liquid preparation step so that the initiation of the phase separation of the low-refractive index layer-forming coating liquid is earlier than the initiation of the phase separation of the antiglare layer-forming coating liquid in the drying step.
