The goal of this paper concerns the evaluation of the efficiency of novel three-component systems for initiating the photopolymerization process of 2-ethyl-2-(hydroxymethyl)-1,3-propanediol triacrylate (TMPTA). Combinations of 1,3-bis(phenylamino)squaraine (SQG1) with different types of co-initiators are proposed as effective UV-Vis light photoinitiators. The co-initiators used in the experiments, such as silane (TTMSS), borate salt (B2), carbazole (NVC) and a set of iodonium salts (I1, I2, I77, I81), are active radical sources for initiation of the polymerization of TMPTA. The effect of the composition of the system on the photopolymerization kinetics was analyzed. The optimal photoinitiator concentration that gives high monomer conversions and high values of the rate of polymerization is indicated and presented in this article.
