Abstract:
The present invention provides an interlayer film for a laminated glass which can suppress bubble formation and bubble growth in the laminated glass. An interlayer film 1 for a laminated glass includes a first layer 2 and a second layer 3 laminated on one face 2a of the first layer 2. Each of the first layer 2 and the second layer 3 contains a polyvinyl acetal resin and a plasticizer. The polyvinyl acetal resin in the first layer 2 is obtained by acetalizing a polyvinyl alcohol resin that has a degree of polymerization exceeding 3000.
