PROBLEM TO BE SOLVED: To provide a liquid composition allowing for formation of a coating film which has sufficient ultraviolet absorption function and infrared absorption function and nonetheless is securely colorless and transparent, and also is excellent in weather resistance, and to provided a production method of the liquid composition, and a glass article having a coating film which has sufficient ultraviolet absorption function and infrared absorption function and nonetheless is securely colorless and transparent, and also is excellent in weather resistance.SOLUTION: A vehicular window glass is provided which comprises a glass substrate composed of soda lime glass, and a coating film formed on the glass substrate and including an infrared absorber and ultraviolet absorber. The vehicular window glass has an ultraviolet transmittance (Tuv) equal to a specific value or less, a solar transmittance (Te) equal to a specific value or less, a visible light transmittance (Tv) equal to a specific value or more, a YI equal to a specific value or less, and a change in the Tuv before and after of a predetermined weather resistance test, equal to a specific value or less. 【課題】紫外線吸収機能と赤外線吸収機能を十分に有しながら、無色透明性が確保され、さらに耐候性にも優れる被膜が形成可能な液状組成物およびその製造方法、並びに紫外線吸収機能と赤外線吸収機能を十分に有しながら、無色透明性が確保され、さらに耐候性にも優れる被膜を有するガラス物品を提供する。【解決手段】ソーダライムガラスからなるガラス基材と、ガラス基材上に形成され、赤外線吸収剤と紫外線吸収剤とを含有する被膜と、を備えた自動車用窓ガラスであって、紫外線透過率（Ｔｕｖ）が特定値以下であり、日射透過率（Ｔｅ）が特定値以下であり、可視光線透過率（Ｔｖ）が特定値以上であり、ＹＩが特定値以下であり、および所定の耐候試験前後のＴｕｖ変化が特定値以下であることを特徴とする自動車用窓ガラス。【選択図】なし
