Abstract:
1. A photo-curable resin composition used for photo nanoimprinting, a fine pattern being formed on a surface of the photo-curable resin composition by a process including: using a mold with a fine pattern formed thereon, bringing a surface thereof on which the pattern is formed into contact with a surface of a resin film, curing the resin film by irradiating light on the resin film; and thus forming the fine pattern on the surface of the resin film, the photo-curable resin composition comprising: a photo-curable resin material containing (meth)acrylate having a structure shown in the structural formula 1 below: a reactive diluent; a photo initiator; and a fluorochemical surfactant, wherein a content of the reactive diluent is not less than 70 parts by weight with respect to 100 parts by weight in total of the (meth)acrylate having the structure shown in the structural formula 1 and the reactive diluent, wherein a viscosity of the composition is 20 mPa·s or less, and wherein the reactive diluent is selected from the group consisting of N-vinyl pyrrolidone, acryloyl morpholine, N,N-dimethylacrylamide, N-methylolacrylamide, N,N-dimethylaminopropylacrylamide, tripropylene diol(meth)acrylate, neopentylgylcol di(meth)acrylate and ethyleneglycol dimethacrylate, wherein the composition has a property that an etching rate by dry etching is 2 nm/s or less.
