An interlayer for laminated glasses which can prevent a glass-surface metallic coating from developing color spots due to a residual alkali metal. It has excellent penetration resistance, hardly changes with time in adhesion to the glass, and hardly generates a buildup (color streaks on the interlayer for laminated glasses). The interlayer for laminated glasses comprises a matrix resin, a liquid plasticizer, acetylacetone, an alkali metal, and at least one metal selected from the group consisting of magnesium and alkaline earth metals, wherein the content of the alkali metal is 20-120 ppm, that of the at least one metal selected from the group consisting of magnesium and alkaline earth metals is 15-60 ppm, excluding 60 ppm, and that of acetylacetone is 0.008 parts by weight or higher per 100 parts by weight of the matrix resin. |
