PROBLEM TO BE SOLVED: To provide a coating liquid for forming an ultraviolet ray-absorbing film having mechanical durability such as abrasion resistance and the like and causing little deterioration in ultraviolet absorptivity due to long-term use, to provide an ultraviolet ray-absorbing glass article for an automobile that has an ultraviolet ray-absorbing film formed using the coating liquid and having mechanical durability such as abrasion resistance and the like and causing little deterioration in ultraviolet absorptivity due to long-term use and to provide a sliding window of an automobile.SOLUTION: The ultraviolet ray-absorbing glass article for an automobile has a glass substrate and an ultraviolet ray-absorbing film including a bond of oxygen and silicon disposed so as to come in contact with the glass substrate on at least a part of the surface of the glass substrate. When conducting a predetermined abrasion test on the surface of the ultraviolet ray-absorbing film, the increment of a cloudy value before and after the test is not more than a specific value and after conducting a predetermined weathering test on the ultraviolet ray-absorbing glass article, the transmittance of light at a wavelength of 380 nm is not more than a specific value.

    【課題】耐摩耗性等の機械的耐久性を有するとともに長期使用による紫外線吸収能の低下が少ない紫外線吸収膜を形成させるための塗布液、およびその塗布液を用いて形成された耐摩耗性等の機械的耐久性を有し長期使用による紫外線吸収能の低下が少ない紫外線吸収膜を有する自動車用紫外線吸収ガラス物品および自動車の摺動窓を提供する。【解決手段】ガラス基材と、ガラス基材の少なくとも一部の表面に、ガラス基材と接するように設けられた酸素とケイ素の結合を含む紫外線吸収膜とを有する紫外線吸収ガラス物品であって、紫外線吸収膜の表面に対して、所定の摩耗試験を行ったときの、試験前後の曇価の増加量が特定の値以下であり、紫外線吸収ガラス物品に所定の耐候試験を行った後の、紫外線吸収ガラス物品の、波長380nmにおける光線の透過率が特定の値以下であることを特徴とする自動車用紫外線吸収ガラス物品。【選択図】なし
