INTERMEDIATE FILM FOR LAMINATED GLASS AND LAMINATED GLASS

摘要

The present invention provides an interlayer film for laminated glass having a monolayer structure comprising only a first layer or a multilayer structure comprising at least two layers including a first layer and a second layer stacked at least on one face of the first layer, wherein the first layer contains a thermoplastic resin and a first plasticizer represented by the formula (1):;;and the interlayer film has a monolayer structure or a multilayer structure including at least two layers and includes the first layer further containing a second plasticizer that is a diester compound, or the interlayer film has a multilayer structure including at least two layers and includes the second layer containing a plasticizer and a polyvinyl acetal resin with a hydroxyl content of 25 to 40 mol %.

1. An interlayer film for laminated glass having
a monolayer structure comprising only a first layer, wherein the first layer contains a polyvinyl acetal resin that is a thermoplastic resin and a first plasticizer represented by the formula (1):in which R1 and R2 each represent an organic group containing at least one ether bond and n represents an integer of 2 to 8, the first layer further contains a second plasticizer that is a diester compound, and
the polyvinyl acetal resin in the first layer has an acetylation degree of at most 30 mol %.
