Abstract
To provide a lens hood 1 which has an antireflection film 4 that is effective for light-shielding of unnecessary light incident on a photographic lens of a camera, and has high designability.SOLUTION: (A) A resin component, (B) particles for forming ruggedness, (B1) inorganic small particles having a particle diameter of 0.05-0.4 μm, (B2) inorganic large particles having a particle diameter of 2-6 μm, and (C) a diluent solvent. A lens hood 1 that is mounted on a subject side of a photographic lens and shields unnecessary light incident on the photographic lens has an antireflection film 4 on an inner wall surface 2a of a hood body 2. The antireflection film 4 is formed of a film having a thickness of 2-40 μm by spray coating formed of a liquid composition. The liquid composition contains (A), (B) and (C). (B) is contained in an amount of 20-60 mass% in 100 mass% of the total amount of the total solid content of the composition. (B) contains 90 mass% or more of (B1) and (B2), and a mass ratio of (B2) to (B1):1 is 1.8 to 3.3.SELECTED DRAWING: Figure 3
