  • UV curable composition for use in 3D printing
    Patent number: 11999865
    Abstract: The present invention relates to photocurable compositions, comprising (A1) a N-vinyloxazolidinone of formula (I), wherein R1, R2, R3 and R4 are independently of each other a hydrogen atom or an organic group having not more than 10 carbon atoms, (A2) optionally one, or more second reactive diluents, (B) one, or more oligomers, and (C) a photoinitiator (C), wherein the amount of component (A1) is 5 to 70% by weight based on the amount of components (A1), (A2) and (B), wherein the viscosity of said photocurable composition is in the range 10 to 3000 mPa·s, preferably 10 to 1500 mPa·s at 30° C. The compositions, from which cured three-dimensional shaped articles having balanced mechanical properties combining stiffness with high toughness can be made, are particularly suitable for the production of three-dimensional articles by stereolithography and photopolymer jetting.
