Three thioxanthone‐based hydrophilic visible photoinitiators (TX‐MPEG350, TX‐MPEG550, and TX‐MPEG750) are prepared and characterized. All of them exhibit excellent water dispersion properties. Real‐time FTIR investigation shows that they can be used as visible photoinitiators for radical polymerization in waterborne systems in the presence and absence of the hydrogen donors. Among them, TX‐MPEG550 has been illustrated as the best hydrophilic visible photoinitiator in the presence of hydrogen donors and would have great potential applications in waterborne visible photocuring systems after carefully investigating the photopolymerization behavior of TX‐MPEGs in different conditions.
