Other solid photoinitiators based phosphine oxides (for example, CGI 403, Ciba) can show a less harmful effect crystallization, but they may also have a lower curing rate. Photoinitiators are crucial to UV curing. 1 Structures Expand this section. Therefore, type I photoinitiators combining the carbazole chromophore to the well-established phosphine-oxides were proposed and studied in this article. A preferred amount of the acyl phosphine oxide photoinitiator and the one or more other photoinitiators, if any, is an amount up to 50 wt %, more preferably 0.1-20 wt %, and most preferably 0.3-15 wt % of the total weight of the UV curable inkjet ink. A similar task force is being considered for amino ketones which are facing the same classification challenges as phosphine oxides. CAS no. A phosphine oxide taskforce has been launched in response to the grouping of phosphine oxides and following threat to the classification of these substances. 2 Names and Identifiers Expand this section. Its CAS Number is 162881-26-7. Those photoinitiators therefore allow the curing of thick pigmented layers. Acylphosphine Oxide Photoinitiator by Agnieszka Ciechacka B.Sc., M.Sc.
