<P>PROBLEM TO BE SOLVED: To provide a coating solution for forming a low-reflective film on a base material, having a low refractive index and low reflectance in the form of a monolayered film and easily forming a large surface area film in a simpler manner, a method for preparing the coating solution, and a low-reflective member produced by using the coating solution. <P>SOLUTION: The coating solution for forming the low-reflective film on a base material comprises a dispersion liquid containing colloidal silica and ≥5 mass% and ≤40 mass% of a tungsten compound in terms of oxide based on the amount of colloidal silica. The coating solution uses rod-like colloidal silica having a major diameter of ≥5 nm and ≤100 nm, spherical colloidal silica having a particle diameter of ≥5 nm and ≤50 nm, and the tungsten compound. <P>COPYRIGHT: (C)2012,JPO&INPIT |
