Abstract: A black resin composition, a cured film, and a black filter are provided. The black resin composition includes: a black coloring agent (A), an ethylenically-unsaturated monomer (B), a solvent (C), a resin (D), a photoinitiator (E), a UV absorber (F), and a surfactant (G). The resin (D) includes a first resin having a weight-average molecular weight of 2,000 to 20,000. The first resin includes a structural unit having a fluorene ring and two or more ethylenically-polymerizable groups. The UV absorber (F) includes a benzylidene-based derivative.

Abstract: A resin composition and a filter element are provided. The resin composition includes a black coloring agent (A), an ethylenically-unsaturated monomer (B), a solvent (C), a resin (D), and a photoinitiator (E). The black coloring agent (A) includes a titanium black (A-1) and a carbon black (A-2). Based on a total usage amount of 100 parts by weight of the titanium black (A-1) and the carbon black (A-2), a usage amount of the titanium black (A-1) is 50 parts by weight to 75 parts by weight.
