Abstract:	本實驗主要目的乃針對聚酯、尼龍等織物製備出一系列含有硝基或胺基苯並咪唑基團之黃色螢光染料。所欲製備之染料可藉由苯二胺，醋酸乙酯等成分經縮合反應後製成2-苯咪唑基醋酸，再與4-N，N-二乙基胺水楊醛行縮合聚合反應後獲得。將所合成之染料以硝酸進行硝化反應後，所得之化合物再以硫化鈉進行還原反應後獲得。自行合成之黃色染料再分別對聚酯(PTT，PET)、尼龍、羊毛、棉等織物進行染色，並評估各種染色堅牢度。由結果得知染料A耐昇華牢度較低，其餘堅牢度性質均合乎商業需求。 The present work aims to investigate and develop a series of coumarin dyes containing nitro or amino benzimidazole group for the polyester and nylon fabrics and so on. Dye A was obtained by the condensing 2-benzimidazolyl acetic acid with4-N, N-diethylamino-salicylaldehyde. Dye B was obtained by nitration with Dye A and nitric acid, and Dye C was obtained by reduction with Dye B and Sodium Sulfide. These dyes were dyed on polyester (PET, PTT), Nylon, Wool and Cotton with different pH value (3, 4, 5, 6) and fastness properties evaluated. The fastness properties of all the dyed samples were in accord with commercial requirements except.
