These coating materials are prepared by the following methods: 1. an UV-reactive dye with UV-curable PU and then cured by UV-radiation; 2. a disperse dye with moisture-cured PU and then top-coated with UV-curable resin. An UV-reactive dye is obtained from the reaction of amino- or hydroxyl-containing disperse dye (e.g. CI Disperse Yellow 9, CI Disperse Orange 3 and CI Disperse Red 1, respectively) with methacrylol chloride, respectively. The dye containing UV-curable coating materials are formulated with UV-reactive dye, UV-curable PU oligomer, reactive diluent (e.g. trimethylolpropane triacrylate, TMPTA) and photo-initiator (e.g. Dacrcur 1173). These UV-curable dye-containing materials are cured with UV light radiation at ambient temperature. The resulting UV-cured coating materials behave better water or solvent-resistance, light-fastness comparing to the conventional disperse dye-containing UV-curing coating system. However, high dye concentration absorbs UV light and prohibits UV-radiation curing. Therefore disperse dye containing moisture-curable PU coating materials are formulated with disperse dyes and moisture-curable PU oligomer, respectively and then cured at ambient temperature, then top-coated with UV-cured PU resin. This system is also evaluated similar to UV-reactive dye containing coating materials. Kan-Nan Chen 陳幹男 2007 學位論文 ; thesis 89 zh-TW |
