LUMINESCENT PHOTOPOLYMER COMPOSITION FOR THREE-DIMENSIONAL PRINTING AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2018 - IPC G03F7/28 G03F7/33 

FIELD: technological processes.

SUBSTANCE: invention relates to the technology of producing optical polymeric materials and can be used for the formation of optical elements by the method of three-dimensional (3D) printing. Luminescent photopolymer composition consists of epoxyacrylate composition (84.0–97.0 wt.%), photoinitiator of polymerization (2.5–3.0 wt.%) and organic-inorganic modifier (0.2–13.0 wt.%), consisting of an inorganic luminescent component and the surrounding organic component. Method of its preparation involves the dissolution of the components in an organic solvent of N,N-dimethylformamide, the formation of a homogeneous solution, the deposition on the surface of the substrate and the drying of the material.

EFFECT: technical result is the low volatility of the composition and the absence of its unpleasant odor.
