Study on the UV Photosensitive of Hexaarylbiimidazole Photoinitiator System

Abstract:

2-chlorohexaarylbiimidazole; sensitizer; hydrogen donor; deeper layer’s curing speed Abstract.The ultraviolet photosensitive initiating system is composed of hexaarylbiimidazole (BCIM), sensitizer and hydrogen donor coinitiator. The effect of sensitizer and hydrogen donor on the curing speed, especially on the deeper layer’s curing speed of ink was studied. The experimental results shown that the deeper layer’s curing speed of the ink system mainly depend on the type and the amount of the sensitizer and the hydrogen donor. The amount of the total initiators in the ink formulation is optimized. This hexaarylbiimidazole initiating system is promisingly useful in silk-screening ink and “green ink” for printing circuit board
