Assignee: FUJIFILM CORPORATION
Field: Optics (Instruments)
Classification: CPC H  B  G | IPC B  G  H

Claim 0:
1. A colored film comprising an uneven structure on a surface,
wherein an average distance between adjacent projections in the uneven structure is equal to or shorter than 1,500 nm,
a standard deviation of the distance between the adjacent projections is 10 to 300 nm,
95.0% or more of the projections satisfy Formula (1),
Formula (1) 3h/D≥1.0,
in Formula (1), h represents a height of the projections, and D represents the average distance between the adjacent projections,
the uneven structure has projections that do not satisfy the requirement of Formula (1), and
a density of the projections that do not satisfy the requirement of Formula (1) is 0.01 to 10/cm2.
