4. The photosensitive composition according to claim 1 ,
wherein the pigment is a chromatic pigment.

5. The photosensitive composition according to claim 1 ,
wherein the pigment is at least one selected from a red pigment, a yellow pigment, a green pigment, and a blue pigment.

6. The photosensitive composition according to claim 1 , further comprising:
a resin having an acid group.

7. A film obtained from the photosensitive composition according to claim 1 .

8. A color filter obtained from the photosensitive composition according to claim 1 .
