There is provided a method of molding which is capable of more highly precisely molding a molded article to be molded such as a lens than conventional technologies.
A molded article such as a lens array and a mold for nanoimprinting is molded by repeating multiple times a transfer step including: a transformation step of bringing a light curable composition containing a compound having a polymerizable functional group and a polymerization initiator into contact with a transfer member 62 on which a transfer shape portion shaped equally to or reversely to an aspherical lens portion 312 is formed to transform the light curable composition to the transfer shape of the transfer member 62; a curing step of irradiating at least a transformed portion of the transformed light curable composition with light by a light irradiation unit 60 to cure the light curable composition; and a separation step of separating the cured light curable composition and the transfer member.
A shaping method is provided by which it is possible to obtain a precisely shaped object, e.g., a lens, that is constituted of a cured object excellent in terms of transparency, etc. and having a small Abbe number. The shaping method comprises a deformation step in which a material to be shaped and a transfer member having a shape to be transferred are brought into contact with each other to deform the material along the shape to be transferred, a curing step in which at least the deformed part of the material is cured, and a separation step in which the material and the transfer member are separated from each other, wherein the steps of transferring the shape to the material to be shaped are repeated a plurality of times. The material to be shaped is a curable composition which comprises (a) fine silica particles, (b) a (meth)acrylate compound having two or more ethylenically unsaturated groups and having no ring structure, (c) a (meth)acrylate compound having two or more ethylenically unsaturated groups and having an aromatic ring structure, and (d) a polymerization initiator, the surface of the fine silica particles (a) having been treated with specific silane compounds (e) and (f).
