<p>To provide a white film which has reflective properties, concealing properties and film-forming stability and can be made into a thin film, a white film, which contains voids therein and satisfies the following formulae (i) to (iii) is provided: 0.6 ‰¤ nB / nA ‰¤ 0.9 20 ‰¤ nA 15 ‰¤ nB
(wherein, nA represents the number of interfaces in 10 µm of the surface layer in the film thickness direction; and nB represents the number of interfaces in ± 5 µm of the central part in the film thickness direction).</p> |
