INTERMEDIATE FILM FOR LAMINATED GLASS AND LAMINATED GLASS

摘要

PROBLEM TO BE SOLVED: To provide an intermediate film for laminated glass capable of suppressing occurrence of foaming of laminated glass and growth of foaming.SOLUTION: An intermediate film for laminated glass has a first layer 2 and a second layer 3 laminated on one surface 2a of the first layer 2. Each of the first layer 2 and the second layer 3 contains a polyvinyl acetal resin or a carboxylic acid-modified polyvinyl acetal resin, or both of the polyvinyl acetal resin and the carboxylic acid-modified polyvinyl acetal resin. Each of the first layer 2 and the second layer 3 contains a plasticizer. When the first layer 2 contains no carboxylic acid-modified polyvinyl acetal resin, the first layer 2 contains a compound having a boron atom.SELECTED DRAWING: Figure 1
