Abstract

A novel evaluation method is investigated for measuring the ability of acid amplification of acid amplifier. The method is based on the measurement of conductivity change by the acid generation according to UV radiation. It is found that the decrease of conductivity is caused by photopolymerization of epoxy monomer during UV curing process of ink film and the 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 is possible to make the dynamical evaluation the curing rate of UV curable ink in curing process by this method.
