A radiation-curable resin composition, suitable for use in 3D printing, and to the production method thereof, i.e. the method for producing three-dimensional objects using radiation by means of 3D printing of the laser, DLP or LCD type, with successive photopolymerisable layers. The radiation-curable resin composition comprises one or more epoxy-acrylic resins and polymethyl methacrylate, graphene, halloysite nanotubes and one or more photoinitiators.

This invention relates to malienated derivatives made from maleic anhydride, functionalized monomers, and one or more additional reagents, e.g., an oxygen-containing reagent (e.g., alcohol, polyol), a nitrogen-containing reagent (e.g., amine, polyamine, aminoalcohol), a metal and/or a metal compound. The invention relates to lubricants, functional fluids, fuels, dispersants, detergents and functional compositions (e.g., cleaning solutions, food compositions, etc.)

There is provided a liquid crystal composition that exhibits a sufficiently low viscosity (), a sufficiently low rotational viscosity (1), and a large elastic modulus (K.sub.33) without decreasing the refractive index anisotropy (n) and the nematic phase-isotropic liquid phase transition temperature (T.sub.ni) and without increasing the solid phase-nematic phase transition temperature (T.sub.cn). The liquid crystal display element that uses this liquid crystal composition satisfactorily obtains a pretilt angle and has a high voltage holding ratio (VHR) and high-speed response. Thus, a liquid crystal display element that has no or less alignment defects and display defects such as image sticking, and has high display quality and high response speed is obtained.
