현재 국내에서 제조 및 유통되고 있는 209종의 수록 화학염색한지의 색상과 색 특성을 조사하고, 2개사로 부터 오방색과 오방간색과 유사한 화학염색한지의 색 견뢰도를 평가하였다. 현재 유통되고 있는 국내 화학염색한지는 먼셀의 10색상이 모두 있었으며, R과 YR 계열 색상이 각각 17 %로 가장 많았고, 이어 Y (15 %), RP (13 %), PB (11 %), GY (10 %), P (5 %), G (5 %), B (3 %), BG (3 %) 계열의 순으로 청색계열의 색상이 가장 적었다. R, YR, G, B, RP 계열의 화학염색한지는 각 계열의 거의 모든 색상의 한지가 제조되고 있었으나, BG, PB, P계열 화학염색한지 의 색상범위는 다른 색상의 화학염색한지 보다 좁았다. 2개사의 오방색과 오방간색 화학염색한지에 대하여 72시간 자외선 조사처리에 의한 색 견뢰도를 평가하였다. 72시간 자외선 조사에 의해 색상이 변한 것은 B사의 자색 화학염색한지의 색상이 9.9RP에서 1.1R로 변한 것 외에는 없었다. 오방색과 오방간색의 화학염색한지에 대해 72시간 자외선 조사 후의 색차는 황색(btY) >> 벽색(btB), 유황색(mY) > 녹색(myG), 홍색(vpR), 자색(dpR) > 적색(srO) > 청색(sB) > 흑색(Bk), 백색(미염색한지 : Wh)의 순이었다. 오방색과 오방간색으로 화학염색한 한지안에서의 색 견뢰도는 황색이 가장 좋지 않으며, 흑색과 백색이 우수하였다.

This study examined the color reproducibility and color fastness of digital textile printing for nylon sublimation transfer. After measuring the temperature and time suited to nylon sublimation transfer, the researchers conducted various tests for comparison and analysis including polyester transfer paper on polyester fabric to check dyeing characteristics, color change, sharpness, and the rubbing fastness of the dyeing samples for nylon sublimation transfer. These tests produced the following results. At 185℃ and 187℃, the sublimation transfer dyeing characteristics of nylon were similar to those of polyester and the researchers even observed superior color development in some colors; at a low temperature of 180℃, the sample that was worked on had the lowest level of color development. The examination of color difference (ΔE), which compared L*a*b* values, showed that the ΔE value of magenta was 10.34, that of yellow was 24.70, and that of black was 15.28. These results highlight the important role of heat treatment temperature and time on color development in nylon sublimation transfer. Concerning sharpness, the samples subjected to higher temperature heat treatment exhibited fewer color spreading phenomena around lines. Thus, dyeing properties and fastness can be enhanced by elongating time at low temperatures and shortening time at high temperatures; however, considering production time constraints as well as the need to produce industrially marketable quantities, the findings of this study suggest that the heat treatment temperature most suitable for nylon sublimation transfer is 187℃ for a duration of 50 seconds.

Diazotization of 2-Amino-5-nitrophenol was Synthesized by the direct diazotization method. The diazonium salts are usually stabilized in the from of double salts. The double salts of zinc chloride are the Commonest, and the double salt method is Specially applicable to the yield-up of coupling. The azo dye(2-naphthol-1-(2'-diazo-5'-nitrophenol)) is Converted into a chromium Complex by heating(100℃) with chromic formate, and DMF. The removal of inorganic salts from dyestuffs was performed in DMF solvent. This effect was more pronounced. From these results, It was obtained to liquid dyestuffs of metal complex with High fastness and high adsorption.
