摘要

PROBLEM TO BE SOLVED: To provide an intermediate film for laminated glass capable of obtaining laminated glass which can suppress occurrence of foam and growth of foam, and to provide laminated glass using the intermediate film for laminated glass.SOLUTION: An intermediate film 1 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 and second layers 2 and 3 contains a polyvinyl butyral resin and a plasticizer. The polyvinyl butyral resin in the first layer 2 is an acetalized substance of a polyvinyl alcohol resin having an average degree of polymerization of more than 3,000.SELECTED DRAWING: Figure 1
