摘要

合成了一种聚甲基丙烯酸树脂

能协同多种分散剂有效地分散彩色滤光片用颜料C.I. P.R254。在颜料浓度为15%(质量分数)时

能将颜料颗粒研磨至粒径为90 nm左右

dpi仅为1.5

并且该高浓颜料液的黏度仅为5 mPas

在室温下能稳定保存至少6个月。该树脂对DisperBYK2000、DisperBYK2001等多种分散剂都有很好的宽容性

而仅有分散剂无树脂则无法达到上述稳定的分散效果。更为重要的是

以该颜料分散液配制的颜料光阻剂具有解析度高(线宽6 m以下)、像素整齐、表面平整的特点

具备实际应用能力。

Abstract

A polyacrylate resin was synthesized that could be used on pigment-dispersion for color filter cooperating with dispersant. The pigment of C.I. P.R 254 was milled to well-distributed particles about 90 nm with 1.5 dpi on 15% concentration. And the dispersed-pigment solution had been much stable in low viscosity on 5 mPas over 6 months at room temperature. Furthermore

the resin can cooperate with many dispersants

such as DisperBYK2000

DisperBYK2001. On the other hand

it couldnt obtain the well-dispersed pigment solution using dispersant merely without the polyacrylate resin. Whats the most important is that the photo resist for color filter using this dispersed-pigment solution above showed high resolution (less than 6 m)

neat edge and flat surface.
