(PROBLEMS TO BE SOLVED BY THE INVENTION) Provided is a light-shielding composition excellent in chemical resistance, light resistance, and insulation suitable for a light-shielding layer of a touch panel and capable of forming an image by photolithography, and a cured film thereof. A copolymer having a plurality of repeating units, which comprises 20 to 90% by mole of a repeating unit represented by the general formula (1) and 10 to 80 moles of a repeating unit derived from at least one polymerizable unsaturated compound copolymerizable therewith (A) having a number average molecular weight of 2,000 to 20,000 and an acid value of 35 to 120 mg KOH / g, and an insulation-treated carbon black (B). Shielding composition for a panel, and is a cured film obtained by curing the above-mentioned light-shielding composition. |
