    • A light nontransparent resin composition for a color filter, and a color filter having a cured film of the composition are provided to improve the prevention of drying at a discharge part, the drying property of a coated substrate, the solubility of solid part and storage stability, to reduce the surface roughness of a color filter and to enhance the uniformity of film thickness. A light nontransparent resin composition comprises a solid part which comprises 8-35 wt% of an acrylic photosensitive resin, 45-65 wt% of a black pigment, 0.003-0.02 wt% of a silicone-based surfactant having an HLB of 8 or less or 0.1-1.0 wt% of a fluorine-based surfactant having an HLB of 8 or less, and a photopolymerization initiator; and 80-90 wt% of a solvent, and has a viscosity of 1.0-10.0 mPa.s at a room temperature. The solvent comprises 30-50 wt% of a solvent having one acetoxy group; 0-25 wt% of propylene glycol diacetate; 30-50 wt% of a solvent having a 3-ethoxypropionic acid structure; and 10-30 wt% of an alicyclic compound having one carbonyl group.
    • 提供了一种用于滤色器的轻不透明树脂组合物和具有该组合物固化膜的滤色器,以改善防止在放电部分的干燥,涂布基材的干燥性能,固体部分的溶解度和储存稳定性 ,以减少滤色器的表面粗糙度并提高膜厚度的均匀性。 轻不透明的树脂组合物包括固体部分,其包含8-35重量%的丙烯酸类感光性树脂,45-65重量%的黑色颜料,0.003-0.02重量%的HLB为8以下的硅氧烷类表面活性剂 或0.1〜1.0重量%的HLB为8以下的氟系表面活性剂和光聚合引发剂; 和80-90重量%的溶剂,并且在室温下具有1.0-10.0mPa.s的粘度。 溶剂包含30-50重量%的具有一个乙酰氧基的溶剂; 0-25重量%的丙二醇二乙酸酯; 30-50重量%的具有3-乙氧基丙酸结构的溶剂; 和10-30重量%的具有一个羰基的脂环族化合物。
