▎ 摘　　要

NOVELTY - A photocurable composition comprises a monomer composition comprising at least one monomer having a refractive index of at least 1.47, preferably at least 1.5, a crosslinker, and a plasticizer. USE - Photocurable composition is used in ink composition for three-dimensional printing for producing inorganic structure, preferably ceramic structure (all claimed). ADVANTAGE - The photocurable composition has high refractive index and improved thermal decomposition property and reactivity to provide excellent cohesion during three-dimensional printing, and produces ceramic structure having excellent thermal stability and mechanical strength. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) photocurable ink composition, which comprises the photocurable composition, a photoinitiator, scaffold particles, and a dispersant; and (2) production of inorganic structure, preferably ceramic structure, involves obtaining the photocurable ink composition, simultaneously or sequentially polymerizing and three-dimensional printing at least one portion of the photocurable ink composition to generate a pre-inorganic polymer, preferably pre-ceramic polymer, and thermally treating at least one portion of the pre-ceramic polymer.
