The development of novel visible light photoinitiators (PIs) with low mobility for 3D printing will open up new applications for photopolymerization. In this work, a polymerizable visible light PI DCCA containing an oxime acryloyl ester structure was designed and synthesized. Its linear absorption has a maximum in the visible region (400-480 nm), overlapping well with the emission spectra of conventional blue light sources, and it can effectively induce acrylate polymerization under irradiation with a 450 nm LED lamp. In addition, migration of DCCA in the 3D printed samples is very low compared with DCCB, which has a similar structure but a phenyl moiety instead of the copolymerizable acrylate as the oxime ester group. The utility of DCCA in 3D printing was demonstrated by printing a 3D object with challenging geometric features with high resolution and accuracy.
