Vol.23, No.2, 309-316, 2006 A study on the application of UV curing ink with sulfonate type acid amplifier
In this paper, both mono-type: 4-hydroxycyclohexyl-4-vinylbenzenesulfonate(CHDv-m), 4-(4-hydroxy-cyclohexyl) cyclohexyl-4-vinylbenzenesulfonate(BCDv-m), 4-(2-(4-hydroxycyclohexyl)propan-2-yl)-cyclohexyl-4-vinyl-benzenesulfonate(IPDHv-m), 4-hydroxycyclohexyl-4-methylbenzenesulfonate(CHDp-m), 4-(4-hydroxycyclohexyl)-cyclo-hexyl-4-methylbenzenesulfonate(BCDp-m) and 4-(2-(4-hydroxycyclohexyl)propan-2-yl)-cyclohexyl-4-methylbenzene-sulfonate(IPDHp-m) and di-type: 4,4'-di(vinylbenzenesulfonatyl)-cyclohexane(CHDv-d), 4,4'-di(vinylbenzenesulfonatyl)-1,1'-bicyclohexane(BCDv-d), 4,4'-di(vinlylbenzenesulfonatyl)-isopropylidene-dicyclohexane(IPDHv-d), 1,4-ditosyloxycyclohexane(CHDp-d), 4,4'-ditosyloxy-1,1'-bicyclohexane(BCDp-d) and 4,4'-ditosyloxy isopropylidene dicyclohexane(IPDHp-d) acid amplifiers were synthesized. Their properties were characterized by 1HNMR and DSC measurements.UV curing properties of samples prepared by using novel acid amplifiers were examined by measuring the change ofcurrent according to UV radiation time and intensity. Also, the application of acid amplifiers to UV inks was suggested.It was found that UV vehicles and inks with acid amplifier of 4-4'di(vinylbenzenesulfonatyl)-cyclohexane(CHDv-d) hada more rapid degree of curing than other samples.
