分别采用与实施例 3相同的方法制备蓝色光阻组合物 -2到 -ια 不同之处 在于采用如表 1中所示组成比例。
蓝色光阻组合物的应用
将实施例 3 ~ 12中制得的蓝色光阻组合物 -1到 -10采用旋转涂布法涂布 在玻璃基板上。 将涂布有蓝色光阻组合物的基板在 90°C温度下烘烤 7分钟 后，采用照度为 250mJ/cm2的紫外线以 25秒的曝光时间对上述蓝色光阻组合 物进行曝光。 将曝光后的玻璃基板在碱性显影液中显影后， 在 200°C温度下 烘烤 30分钟， 形成厚度为 1.5μηι的蓝色子像素图形 1 ~ 10。

表 1
Figure imgf000011_0001
结合以上表格的结果可以看出， 当着色剂与红外光发射材料的比大于 6 时， 红外线比辐射率偏低， 如实施例 3和实施例 4, 同时由于着色剂含量过 高， 因此透过率偏低。 对于实施例 12, 同样由于红外光发射材料含量偏低， 因此红外线比辐射率偏低， 同时由于着色混合材料含量偏低， 特别是着色剂 含量偏低， 因此色度偏低 (y较大：)。
当着色混合材料内红外光发射材料的含量低时， 光阻组合物的红外线比 辐射率也低， 随着着色混合材料内红外光发射材料含量的增加， 光阻组合物 的红外线比辐射率增大， 但均未对光阻材料的透过率造成明显影响。
未经表面处理和经表面处理的红外光发射材料对光阻稳定性的影响 对比例 1
将 5g BYK 161加入至 95g溶剂丙二醇单曱基醚醋酸酯 (PMA)中， 向其加入 11. lg的氧化铝颗粒。 该混合物经搅拌均匀后， 置于砂磨机中研磨 粉碎至氧化铝的平均粒径为 17nm, 得到氧化铝纳米分散溶液。 去除该氧化 铝纳米分散溶液中的溶剂， 得到氧化铝纳米颗粒。 将蓝色颜料 RB.15:6与上述氧化铝纳米颗粒以 19: 1的重量比混合得到着 色混合材料。
按照实施例 3的方法制得对比蓝色光阻组合物。
将实施例 3和对比例 1制得的两种蓝色光阻组合物置于 0 ~ 4°C的避光环 境中， 观察光阻组合物的分层和沉淀现象。
对比蓝色光阻组合物： 24小时后， 表面出现结皮现象， 且容器底部有少 量沉淀； 48小时后， 搅拌时出现大量结块， 固体颗粒团聚严重。
蓝色光阻组合物 -1: 直至 48小时， 均未发现表面结皮或底部沉淀现象， 搅拌未出现结块及团聚现象。
综上所述， 根据本发明的能发射红外光的蓝色光阻组合物通过添加经过 表面改性的红外光发射材料的纳米颗粒，可发射具有保健作用的远红外光线， 同时保持了常规的显示性能。
