(57) Abstract: A method of spatially modulating light intensity, such as a mask exposure method or an interference exposure method, to obtain at least one of a density, a refractive index, an uneven shape, and an alignment state of a polymer. To provide a photopolymerizable composition capable of forming a pattern of 100 μm or less, particularly a pattern of 10 μm or less as a minimum resolution in a spatial distribution of physical quantities. SOLUTION: As a constituent of the composition, a polymerization initiator, A light comprising at least one polymerizable compound and at least 1% by weight to 50% by weight, preferably from 5% by weight to 30% by weight, based on the total amount of the polymerizable compound, of one or more polymerization retarders. A polymerizable composition, a method for producing an optically functional film using the composition, and an optically functional film. |
