Double-centre cationic photoinitiator, method for obtaining double-centre cationic photoinitiator, and a photocuring coating composition containing the double-centre cationic photoinitiator

摘要

the object of the application is kationowy dwucentrowy photoinitiator, in the form of di (heksafluoroantymonianu00f3w) dijodoniowych of general formula a: - and + - x - and + - 2yf6 -, where x is a group fenylowu0105, in positions 1 and 4, or a bifenylowu0105 group in position 4 and 4 'jodoniowym centres, with the rest of the kumarynowu0105 requesting means, which is 7 - methoxy - 4 - metylokumaryna or 7 - benzyloxy - 4 - metylokumaryna.the notification includes manufacture of a photoinitiator, which method involves the following steps: mixing acetonitrile with hydroksytosyloksydijodoarenem and obtaining component 1; mixing component 1 of coumarin at boiling temperature for 8 hours to 16 hours.and to obtain the component 2; mixing component 2 with the solution heksafluoroantymonianu sodium or potassium heksafluoroantymonianu in chloroform from 30 min to 6 hours and obtain the component 3; component 3, mixing with distilled water during the 30 min to 6 h separable organic layer; wydzie lena obtained organic layer of a photoinitiator dwucentrowy cation in the form of di (heksafluoroantymonianu00f3w) dijodoniowych of general formula.the object of the application is also powu0142okowa fotoutwardzalna composition containing substance bu0142onotwu00f3rczu0105 oksetanowu0105 epoxy, vinyl, allilowu0105 and / or propenylowu0105 and plasticisers and / or solvents and / or auxiliary substances, is characterized by the fact that contains fotoin icjator kationowy dwucentrowy in quantities of from 0.5 to 5% by weight of the dry weight of the composition powu0142okowej,and plasticisers and / or solvents and / or excipients in amounts from 0 to 75% by weight of the composition powu0142okowej.
