Study on the Curing Kinetics of UV-Curable Inkjet Ink

In order to make different UV curing inkjet ink system and test the relationship between the dynamic elastic modulus and UV curing time, the same monomer and pre-polymer were mixed in different proportions, and different functional monomers and pre-polymer were mixed. The results show that the larger the proportion of the pre-polymer and the greater the number of monomer functional groups, the shorter the induction period of the UV curing of UV inkjet ink system and the faster the UV curing rate. Then, the UV curing kinetics of UV inkjet inks was analyzed preliminarily.
