Abstract

See full text

A film (1) includes hollow particles (10) and a binder (20). The hollow particles are made of a material having a refractive index of 1.15 to 2.70. The binder (20) is formed of at least a polysilsesquioxane and binds the hollow particles (10). The film (1) satisfies at least one of requirements Ib/Ia≥0.7 and Ib/Ic≥0.3. Ia is an absorbance derived from a hydrocarbon group not directly bonded to a silicon atom, the absorbance being determined by attenuated total reflection using a Fourier transform infrared spectrophotometer. Ib is an absorbance derived from a bond between a silicon atom and a non-reactive functional group. Ic is an absorbance derived from a bond between a silicon atom and a hydroxy group.
