<p>The aim of the invention is to supply a lightproof combination with high lightproof performance and excellent insulating ability and dispersible stability and a colour filter adopting the combination. The benzimidazolone dioxazine pigment expressed by general formula (1) is taken as the tinting material of the necessary components. In the solid content containing over 40wt% lightproof combination, the optical density of the solidified film, when the film thickness is over 2.0, (in the formula, R1 and R2 respectively and independently express a hydrogen atom or an alkyl with substituent, and X expresses a hydrogen atom or a halogen atom).</p> |
