    摘要: 一、自行合成含異氰酸酯之無軟鏈段之水性PU預寡聚物，利用分子結構上含有的羥基或胺基的分散性染料與PU樹脂上的異氰酸酯基反應形成含染料之水性化的高分子染料分散液，以TMPTA-AZ作為架橋劑可成為自行架橋型水性高分子染料分散液，在乾燥過程中會產生高分子架橋交聯反應，形成耐水性耐溶劑之水性PU染料。
    二、另外合成出含有雙鍵的反應性染料，摻混入紫外光硬化型PU樹脂，形成紫外光硬化型染料，經由紫外光照射硬化提供快速方便的製程，形成耐水耐溶劑的高分子染料。
    高分子染料薄膜進行各種測試: 膠含量、吸水率、對水損失率、乙醇吸收率、對乙醇損失率、熱重分析等，並探討其水性高分子染料分散液應用於書寫之可行性。
    本論文探討非溶劑型高分子染料，利用紫外光硬化及常溫架橋劑進行架橋反應，形成耐水及耐溶劑之高分子染料。
    This research is aiming at non-solvent type polymeric dyes become water-resistant and solvent-resistant polymeric dyes by self-curing and UV-curing processes. First, the carboxyl group containing aqueous-based polymeric dyes dispersions were prepared from a reaction between isocyanate group of PU prepolymer and the hydroxyl or amine group of a disperse dye. Self-curable aqueous-based polymeric dye is formulated by mixing the aqueous-based polymeric dye with a curing agent, TMPTA-AZ. The stable aqueous-based polymeric dye becomes water-resistant and solvent-resistant inks by cross-link reaction on drying dispersion. Second, an acrylate containing dye was synthesized. A UV-curable polymeric dye system can be prepared by mixing this reactive dye with UV-reactive PU oligomer and photoinitiator. This UV-curable polymeric dye provides for a convenient process obtaining a water-resistant and solvent-resistant polymeric ink.
    All the polymeric dye films before and after curing were evaluated by the measurement of gel content, water absorption, alcohol uptake and thermal stability. Finally, the aqueous-based polymeric dye PU dispersions as an ink for writing applications.
