Title:
PEGYLATED THIOXANTHONE PHOTOINITIATOR AND PHOTOSENSITIVE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/001268
Kind Code:
A1
Abstract:
The present invention discloses a PEGylated thioxanthone photoinitiator and a photosensitive resin composition. The PEGylated thioxanthone compound is low in toxicity, environmentally friendly, and leaves little residue after curing as a photoinitiator. The compound can improve the compatibility of the photoinitiator with photosensitive resin composition systems, and has high initiation efficiency and good thermal stability. The present invention provides a photosensitive resin composition with appropriate composition and contents, enabling printing of hydrogels with specific structures in 3D. The hydrogels have lower cytotoxicity and better biocompatibility, and can be applied to bioengineering fields such as 3D cell cultures.
