Patent ID: 7824740

Claim:
An anti-reflection film producing method comprising: a coating applying step of applying coating solution to a long support, said coating solution containing a polymerizable compound, and at least first and second polymerization initiators which absorb actinic radiation of wavelength ranges different from one another and generate a radical in response thereto; an ultraviolet radiation curing step of, after drying a coating layer formed by said coating applying step to a reference dry state, applying ultraviolet radiation to said coating layer, to obtain an anti-reflection layer by ultraviolet curing of said polymerizable compound; wherein said ultraviolet radiation curing step includes first processing and second processing subsequent to said first processing; in said first processing, two or more optical filters having wavelength selectivity are arranged in a web width direction of said long support, for adjusting a deviation of an amount of ultraviolet radiation to said coating layer in said web width direction into a range equal to or more than 1% and equal to or less than 10% of an average amount, and in said first processing, said radical is generated from said first polymerization initiator, wherein in said second processing, said radical is generated from said second polymerization initiator.
