Curable composition for sheet, cured product and production method thereof, three-dimensional molding sheet, optical member, lenticular sheet, and three-dimensional structure

摘要

One embodiment of the present invention has a functional group containing a nitrogen atom and a polymerizable group, a polymerizable compound having a molecular weight of 300 or less, and two or more (meth) acryloyl groups other than the polymerizable compound. It contains a functional monomer and a radical photopolymerization initiator, and does not contain a urethane (meth) acrylate compound, or the content of the urethane (meth) acrylate compound is based on the total mass of the curable composition for a sheet, Provided is a curable composition for a sheet used for three-dimensional molding, which is more than 0% by mass and less than 4% by mass, and its application.
