Abstract
A pattern is formed on a substrate with forming a layer of a curable composition (A) containing a component (a) serving as a polymerizable compound on a surface of the substrate, then dispensing droplets of a curable composition (A) containing a component (a) serving as a polymerizable compound (a) and a component (b) serving as a photopolymerization initiator dropwise discretely onto the layer of the curable composition (A), subsequently sandwiching a mixture layer of the curable composition (A) and the curable composition (A) between a mold and the substrate, then irradiating the mixture layer with light to cure the mixture layer, and then releasing the mold from the mixture layer after the curing.
