摘要 |
A polyimide resin composition for an optical filter which includes a colorless transparent polyimide resin containing at least one perfluoroalkyl group in each recurring structural unit and having excellent solvent solubility, and at least one dyestuff soluble in said resin. The dyestuff has absorption in the visible range and/or the near infrared range. A printing ink for an optical filter is composed of the polyimide resin composition and a solvent while an optical filter formed from a transparent base material and the polyimide resin composition can also be provided.
