To investigate in influence of photosensitizer used with benzophenone(BP) in the curing rate and physical properties of UV curable hard coating on plastic, we prepared UV curable clear and pigmented coatings with DEA, DMA, NPM and TEA as photosensitizer, respectively. The curing rate calculated from the decrease of the absorbance of acrylic double bond measured by FT-IR spectroscopy increased s follows; DEA>DMA>NPM>TEA. this order could be explained by the reactivity of diethylamino group of DEA and the ease of formation of activated complex between BP and photosensitizer during the curing process. In UV curable pigmented coatings, the order of curing rate increased as follows; DEA>DMA>TEA>NPM. It was found that the curing rate of the pigmented coating can be increased by light scattering of TiO$_2$. The hardness of coating film cured by photosensitization of DEA and DMA is higher than other photosensitizers due to the crosslinking reaction of DEA and DMA radical bound to polymer backbone.

The polarizer is an important optical element used in a variety of applications. Nano-wire grid polarizers in the form of sub-wavelength metallic gratings are an attractive alternative to conventional polarizers, because they provide high extinction ratio. This study has been carried out to fabrication of the 17inch area size nano-wire grid polarizer(NWGP) The master for NWGPs with a pitch of 200nm and the area size $730mm{\times}450mm$ were fabricated using laser interference lithography and aluminum sputtering and wet etching. And The NWGP fabrication process was using by the Roll to-Roll UV imprinting and was applied to flexible PET film. The results were a transmission of light (Tp) 46.7%, reflectance (Rs) 40.1% and Extinction ratio of above 16 for the visible light range.

Surface sizing is one of the important process to the paper making. Surface sizing had an effect on penetration of oils, physical propertiesm water resistance for the paper. This study was carried out for the purpose of improving printability with surface sizing of domestic newspaper. The samples were prepared by means of TAPPI method(TAPPI 205 om~88), and were wested by IGT printability tester. The results of this study showed that the set-off was reduced on the surface sized with oxidized starch.

얼마 전 미국에서 오프라인 UV코팅 가격정책과 관련한 보고서가 발간됐다. 이 보고서는 가격정책에 대한 지침을 보여줄 뿐만 아니라 코팅 작업의 절차와 구성, 그리고 솔루션에 대한 이슈를 모두 다뤘다. 특히 미국의 UV코팅 작업단가가 우리나라와 마찬가지로 치열한 경쟁 속에 엄청나게 낮은 수준까지 떨어져 있다는 점은 눈길을 끌었다.

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.

With increasing interests in environment matters over the world, incessant efforts to develop products which meet these environmental requirements have been made also in paint industry. Among the efforts in this field, UV(Ultra Violet) curing system is focused as one of most potential system. It is because this system not only proved to be environmentally friendly compared with heat curing system or other system but also has economical merit of smaller facility, less energy consumption, and better productivity. Superior properties in many application is surely one of its dominant merit. With these advantage UV system is applied to a variety of industrial fields and expected to have continuous growth in the future. As practical application of UV system has shown lasting progress, R&D on basic material of this system keeps up with. This is a study on photo-initiator that is a fundamental substance in UV curing method and amine, its aid for better effect. After reviewing on them in the aspects of function, economy, and stability, optimal foumula is pursued through experiments when applied to real products.
