Title:
INTERMEDIATE FILM FOR LAMINATED GLASS, AND LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2015/125931
Kind Code:
A1
Abstract:
Provided is an intermediate film for laminated glass, which is capable of suppressing excessive adhesion to an intermediate film or the like, and which is also capable of increasing transparency.
An intermediate film for laminated glass according to the present invention is obtained by mixing a first composition which contains a first thermoplastic resin having a hydroxyl group and a plasticizer with a second composition which contains a second thermoplastic resin having a hydroxyl group and a plasticizer. The hydroxyl group content ratio of the first thermoplastic resin is higher than the hydroxyl group content ratio of the second thermoplastic resin. The ratio of the complex viscosity of the second composition at 200°C to the complex viscosity of the first composition at 200°C is less than 4.5.
