PURPOSE: To form a coating film containing fine inorganic compound particles in the form of monodisperse particles on, e.g. a glass or plastic base material by dispersing or dissolving fine inorganic compound particles or a specified matrix in water or an organic solvent and specifying the ion concentration.
CONSTITUTION: A coating fluid prepared by dispersing or dissolving fine inorganic compound particles and/or at least one matrix selected from among partial hydrolyzates of an acetylacetonato chelate, an alkoxysilane and a metal alkoxide in water and/or an organic solvent and adjusting the ion concentration in such a manner that at most 10mmol of ions are present per 100g of the total solid matter of the fluid. This fluid can give a coated base material prepared by forming a coating film on a base material, especially one excellent in antireflection and antistatic properties.
