There are provided a liquid composition capable of forming a coating film securing colorless transparency, being excellent in weather resistance, suppressing occurrence of bleedout, and having sufficiently ultraviolet absorbing function and the infrared absorbing function, and a glass article having a coating film formed by this composition. A liquid composition for forming a coating film contains an infrared absorbent selected from a tin-doped indium oxide, an antimony-doped tin oxide, and a composite tungsten oxide; an ultraviolet absorbent selected from a benzophenone-based compound, a triazine-based compound, and a benzotriazole-based compound; predetermined amount of a dispersing agent having a molecular weight of 1,000 to 100,000; predetermined amount of a chelating agent relative forming a complex with the infrared absorbent and having a molecular weight of 1,000 to 100,000, the complex exhibiting substantially no absorption with respect to light having a visible wavelength; a binder component; and a liquid medium.

Liquid composition and glass article

To provide a liquid composition capable of forming a coating film which has sufficient ultraviolet-absorbing ability and infrared-absorbing ability. A liquid composition for forming a coating film comprising an infrared absorber selected from indium tin oxide, antinomy tin oxide and a composite tungsten oxide, an ultraviolet absorber selected from a benzophenone compound, a triazine compound and a benzotriazole compound, a dispersing agent having an acid value and/or an amine value, a binder component and a liquid medium, wherein the dispersing agent is contained in a content such that the product of the sum (mgKOH/g) of the acid value and the amine value of the dispersing agent, and the mass ratio of the dispersing agent to the infrared absorber, is from 2 to 30 (mgKOH/g).
