Methods for producing an optical element having a cured layer with a concavo-convex structure are described. Such a method includes: forming a composition layer on a base material by using a composition containing a polymerizable compound and a photo initiator; forming a pattern formative layer by pressure-contacting a mold; and forming the cured layer having the concavo-convex structure by photo-curing the pattern formative layer, wherein the polymerizable compound contains (a) a urethane (meth)acrylate monomer, the composition contains 0.005 to 0.5 part by mass of the photo initiator with respect to 100 parts by mass of the polymerizable compound, and the cured layer has a film thickness of the concavo-convex structure within a range of 0.5 mm to 1 cm.

Composition and film

Described is a composition comprising: a compound (A) having a substituent (a) being at least either one of an acryloyl group and a methacryloyl group, and a perfluoroalkylene group; and a compound (B) having a substituent (b) being either one of an acryloyl group and a methacryloyl group, and a substituent (c) being either one of an acryloyl group and a methacryloyl group.

Composition, resin mold, photo imprinting method, method for manufacturing optical element, and method for manufacturing electronic element

A suitable combination of a composition for formation of a resin mold with a pattern and a composition for formation of resin to which the pattern is transferred from the resin mold is found.

Composition

Compositions are for formation of etch-resistant resins. Such resins are useful for manufacturing components or devices.

Composition and a method for manufacturing a component

A curable resin composition comprising: a fluorinated urethane(meth)acrylate represented by formula (1), wherein, R, R, Rand Reach independently represents a hydrogen atom or a methyl group, x and y each independently represents 1 or 2, and n represents an integer within the range of 1 to 10; Rand Reach independently represents the hydrogen atom when x and y are both 1; Rrepresents the hydrogen atom and Rrepresents the methyl group when x is 1 and y is 2; Rrepresents the methyl group and Rrepresents the hydrogen atom when x is 2 and y is 1; and Rand Reach independently represents the methyl group when x and y are both 2.
