Title:
INTERLAYER FOR LAMINATED GLASS, AND LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2011/081191
Kind Code:
A1
Abstract:
Disclosed is an interlayer for laminated glass. Said interlayer can inhibit bubble formation and bubble growth in laminated glass. The disclosed interlayer (1) is provided with a first layer (2) and a second layer (3) which is laminated onto one surface (2a) of the first layer (2). The first and second layers (2, 3) contain a polyvinyl acetal resin and a plasticizer, respectively. Measuring the viscoelasticity of a resin film (with a glass transition temperature Tg (°C)) which either is the aforementioned first layer (2) or contains 100 parts by weight of the polyvinyl acetal resin from the first layer (2) and 60 parts by weight of a triethylene glycol di-2-ethylhexanoate (3GO) plasticizer, the elastic modulus G'(Tg+80) at a temperature of (Tg+80)°C is at least 65% of the elastic modulus G'(Tg+30) at a temperature of (Tg+30)°C.
