Abstract:
A dispersion composition is provided in which the dispersibility of titanium black is high, the sedimentation of titanium black over time is suppressed, and overall dispersibility and storage stability are high. Further, a polymerizable composition is provided in which favorable coating property on a substrate and even film thickness can be obtained, generation of residue in an unexposed region when a pattern is formed can be suppressed, and favorable pattern shape having any steps after exposure/development can be obtained. The dispersion composition contains (A) titanium black, (B) a graft copolymer and (C) a solvent.
