Abstract:

The purpose of the present invention is to provide: an interlayer for laminated glass, having engraved line-shaped recessed sections on both surfaces thereof, being able to exhibit excellent de-aeration characteristics during laminated glass production, and being capable of suppressing the occurrence of moiré patterns when unwound from a rolled state; laminated glass using said interlayer for laminated glass; an embossing roll production method suitable for the production of said interlayer for laminated glass; and a production method for said interlayer for laminated glass. This interlayer for laminated glass has a plurality of recessed sections on both surfaces thereof. The recessed sections have a floor section having a continuous trench shape; the continuous trench-shaped recessed sections of adjacent floor sections are regularly aligned in parallel; and the glossiness of the surface having the plurality of recessed sections is more than 3% as measured in accordance with JIS Z 8741-1997 or the haze value for the interlayer for laminated glass is no more than 87% as measured in accordance with JIS K 7105-1981.
