Oxime photoinitiator
WebIn this current contribution, we provide a detailed investigation into the photochemistry and the free radical photoinitiating reactivity of LED light-sensitive photoinitiators (PIs). This series was designed on the basis of a judicious association of a carbazole-coumarin fused subunit and an O-acyl-α-oxooxime branch, which integrates an N–O photocleavable bond. … Web• The consortium now includes many photoinitiator manufacturers, distributors and downstream users based in North America, China and Europe. • PIP is engaged in several programs, including: ... • Novel oxime esters • Synergists for oxime esters • Nanoparticulate photoinitators • Silylated PIs • LED-curable cationics • Quantum ...
