Provided are: a glass laminate for a vehicle window glass, which has a coating film that has an appropriate film thickness distribution in the vertical direction and good crack resistance; and a method for producing the glass laminate. A glass laminate provided with a coating film having an upper side along the upper side of a glass substrate and a region of a specific size having a longitudinal size of more than 100 mm, the coating film has a film thickness distribution in at least a portion of the region of the specific size: the film thickness of the coating film in a region between the upper edge of the coating film and a first imaginary line obtained by translating the upper edge of the coating film downward by 20 mm along the surface of the coating film is greater than 0 [mu] m and 2.0 [mu] m or less; the film thickness of the coating film in a region on and below a second imaginary line obtained by translating the upper edge of the coating film downward by 100 mm along the surface of the coating film is 2.0-3.0 [mu] m.
本发明提供一种具有上下方向上的膜厚分布适宜且耐裂纹性良好的被膜的车辆窗玻璃用的玻璃层叠体及其制造方法。一种玻璃层叠体,其具备具有沿着玻璃基材上边的上边和纵向尺寸大于100mm的特定尺寸区域的被膜,该被膜在特定尺寸区域的至少一部分中具有以下膜厚分布:被膜的上边与使被膜的上边沿着被膜的表面向下方平移20mm而得的第一假想线之间的区域中被膜的膜厚大于0μm且在2.0μm以下,使被膜的上边沿着被膜的表面向下方平移100mm而得的第二假想线上以及第二假想线下方的区域中被膜的膜厚为2.0~3.0μm。
