titanium black;
a monomer A which is a non-aromatic heterocyclic compound having an ethylenically unsaturated double bond;
a monomer B which is an alicyclic compound having an ethylenically unsaturated double bond; and
an acidic dispersant.
2. The method of manufacturing a light shielding film according to claim 1 ,
wherein the ink has a content of the monomer B of 35 mass % to 200 mass % with respect to a content of the monomer A.
3. The method of manufacturing a light shielding film according to claim 1 ,
wherein a content of the monomer A is 10 mass % or greater with respect to a total amount of the monomers in the active energy ray curable-type ink jet ink.
