The present invention provides an antifouling film that is excellent in antifouling properties, rubbing resistance, and adhesion. The antifouling film includes: a substrate; and a polymer layer disposed on a surface of the substrate and including on a surface thereof an uneven structure provided with projections at a pitch not longer than a wavelength of visible light, the polymer layer being a cured product of a polymerizable composition, the polymerizable composition containing, in terms of active components, 30 to 80 wt % of a polyfunctional acrylate, 10 to 30 wt % of a monofunctional amide monomer, 0.5 to 10 wt % of a fluorine-based release agent, and 5 to 30 wt % of a vinyl-based polymer containing a repeat unit represented by a predetermined formula.

The present disclosure aims to provide a novel surface modifier that can be introduced into a photosensitive resin composition to improve the surface roughness of a fluororesin suitable for use as a partition wall material. The present disclosure relates to a surface modifier containing a fluororesin (A) having a structure represented by the following formula (1):

##STR00001##

wherein each Ra independently represents a C1-C6 linear, C3-C6 branched, or C3-C6 cyclic alkyl group or a fluorine atom, and any number of hydrogen atoms in the alkyl group are replaced with fluorine atoms.

Provided is a liquid-repellent agent which enables the production of partition walls that are less susceptible to reduction in liquid repellency even when subjected to oxygen plasma treatment or UV-ozone treatment. A liquid-repellent agent (A) of the present invention contains a polymer containing: a polymerization unit (a1) derived from a hydrocarbon having an alkyl group in which at least one hydrogen atom is replaced with a fluorine atom and which may contain an ether-oxygen atom; and one or two or more types of polymerization units (a2) other than the polymerization unit (a1), wherein the number of ethylenically unsaturated double bonds in the polymerization units (a1) and (a2) is 3 or greater.

Photosensitive compositions containing nanosized light emitting materials and (meth)acrylic polymer are suitable for use in a variety of optical applications, for example the preparation of quantum material doped photoresist films, especially for optical devices. Optical films can be prepared be by: a) providing the photosensitive composition onto a substrate, and b) polymerizing the photosensitive composition by exposing the photosensitive composition to radiation.
