Abstract
A photocurable composition can comprise a polymerizable material and a photo-initiator, wherein the polymerizable material can comprise at least one multi-functional vinylbenzene in an amount of 15 wt % to 85 wt % and at least one multi-functional acrylate monomer in an amount of 15 wt % to 85 wt % based on the total weight of the photocurable composition. A photo-cured layer of the photocurable composition can have a high heat stability up to 400° C. and a glass transition temperature of at least 135° C.
