Abstract
An interlayer film for laminated glass of the present invention contains a thermoplastic resin and a dispersant, wherein the dispersant is unevenly distributed in such a manner that its concentration is low in an outer surface of the interlayer film for laminated glass. According to the present invention, the interlayer film for laminated glass capable of preventing, even when the water content of peripheral portion of a laminated glass increases to about 1.5%, a decrease in pummel value so that separation between a glass plate and the interlayer film is prevented and the function of the laminated glass is successfully maintained can be provided.
