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.

산증식제가 가지고 있는 산증식 능력을 측정하기 위한 새로운 평가 방법이 연구되어지고 있다. 그 방법은 UV 조사에 따른 산의 발생으로 인한 전도도 변화를 측정하는 것에 그 원리를 두고 있다. 본 연구자는 실험을 통해 다음과 같은 사실을 알 수 있었다. Inks film의 UV 경화반응 동안의 epoxy monomer의 광중합과 UV 경화율에 의해 전기 전도도가 감소하게 된다는 것이다. 본 논문에서는 새로운 산증식제를 합성하고, 합성된 산증식제의 열적 안정성을 DSC로 측정하였다. 여기서는 mono-type의 산증식제가 di-type의 산증식제보다 열적으로 더 안정하였다. 이러한 결과를 바탕으로 경화과정에 있어 UV 경화형 ink의 경화속도를 동적으로 평가할 수 있었다.
