Title:
GLASS LAMINATE AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2022152138
Kind Code:
A
Abstract:
To provide a glass laminate capable of excellently shielding ultraviolet rays and infrared rays, improved in weather resistance and light resistance, and capable of suppressing a decrease of visible light transmittance during use.SOLUTION: A glass laminate (1) is characterized in that an ultraviolet and infrared shielding film (20) containing silica, an ultraviolet shielding agent and infrared shielding particles (20P) is formed on a surface (10S) of a glass plate (10); in at least a partial region of an upper end located within 5 cm from an upper edge side of the glass plate of the ultraviolet and infrared shielding film (20), when the ultraviolet and infrared shielding film is viewed in the depth direction from the film surface of the ultraviolet and infrared shielding film, a concentration of optionally selected one or more metal elements contained in the infrared shielding particles present between the film surface and a depth of 50% from the film surface is 55 atomic% or more; and a concentration of the one or more metal elements contained in the infrared shielding particles present between the film surface and a depth of 10% from the film surface is 12 to 20 atomic %.SELECTED DRAWING: Figure 3
