PROBLEM TO BE SOLVED: To provide a coating liquid for forming a solar radiation-screening film which may adapt to the existing transparent bases, may form a coating film at an ordinary temperature and yields an excellent film strength, a solar radiation-screening film formed using this coating liquid having a high solar radiation-screening ability and a high surface hardness, and a base having a solar radiation-screening ability. SOLUTION: The coating liquid for forming a solar radiation-screening film contains binder components, a diluent solvent, a curing catalyst and a near infrared ray-screening component. Here, at least one of the binder components is a substance of formula 1 obtained by mixing and reacting a glycidoxypropyl group-containing alkoxysilane and an aminoproply group-containing alkoxysilane, and the near infrared ray-screening component is a fine particle having an average particle size of <=100 nm comprising a ruthenium oxide-containing fine particle, an iridium oxide-containing fine particle and/or a rhodium oxide- containing fine particle.
