Abstract
A novel evaluation method was investigated for measuring the ability of acid amplification of acid amplifier. The method was based on the measurement of conductivity change by the acid generation according to UV radiation. It was found that the decrease of conductivity was caused by photopolymerization of epoxy monomer during UV curing process of ink film and by the rate of UV curing. In this paper, the novel acid amplifiers were synthesized and measured thermal stability by means of DSC. It was found that mono-type acid amplifiers were more stable than di-type. It was possible to make the dynamical evaluation of the curing rate of UV curable ink in curing process by this method.
