“…One of the basic methods for increasing the solubility of traditional radical photoinitiators is their chemical modification, which consists of adding appropriate groups to the structure of the photoinitiator [88] [89-91]. The groups designated for this purpose are: non-ionic ethers, polyethers, hydroxyethers [92], ionic substitutes such as quaternary ammonium salts, sulphonates, carboxylic acids, and thiosulphates [93][94][95]. The most common solubilising group is the hydroxyl group, which can be found in the most popular water-soluble initiator: Irgacure 2959 -2-hydroxy-1-[4-(2-hydroxyethoxy) phenyl]-2-methyl-1-propanone.…”

“…UV-curing technology has drawn more and more attention in many fields such as coatings [ 1 , 2 , 3 , 4 , 5 ], 3D printing [ 6 , 7 ], biomaterials [ 8 ] because of its environmentally friendly and high efficiency advantages. A conventional UV-curing system usually is a composition of UV-curable polymers, reactive monomers, additives, and a photoinitiator or photoinitiator system [ 9 ]. The UV initiator or initiator system is critical because it determines the UV-curing speed and significantly affects the comprehensive performance of cured materials such as yellowing, odor, migration, etc., [ 9 , 10 , 11 , 12 ].…”

“…The UV initiator or initiator system is critical because it determines the UV-curing speed and significantly affects the comprehensive performance of cured materials such as yellowing, odor, migration, etc., [ 9 , 10 , 11 , 12 ]. Small molecule UV photoinitiators such as benzoin, acetophenone, α-hydroxy ketone, benzophenone, thioxanthone, and their derivatives have been widely used [ 6 , 8 , 9 , 10 , 11 , 12 ], however, their obviously disadvantages such as relatively strong odor and high migration from cured films greatly limit their applications [ 10 , 13 , 14 , 15 , 16 , 17 , 18 ]. Especially, the unreacted small molecule photoinitiator molecules and photolysis products can migrate to the surface of post-cured material or may be extracted into liquid-packed goods when the UV-cured materials were applied in food packaging [ 14 , 19 ].…”

“…[1][2][3][4][5][6] The photoinitiator plays a critical role in controlling photopolymerization rate, and the feature of the photoinitiator directly affects other aspects of the formulation. At present, watersoluble small-molecular photoinitiators deriving from conventional photoinitiators involving benzoin, acetophenone, thioxanthone, α-hydroxyketone, and benzophenone have some apparent drawbacks such as high migration from cured films, relatively strong odor and yellowing, which strongly limit their applications.…”
