An interlayer film for laminated glass is disclosed which contains a thermoplastic resin and has a portion where the amount of increase in the thickness is increased in a direction from one end to the other end in the region where the thickness is increased, or has a portion where the amount of increase in the thickness is decreased in a direction from one end to the other end in the region where the thickness is increased, and the ten-point average roughness Rz of the surface at a center position of the portion where the amount of increase in the thickness is increased, or the portion where the amount of increase in the thickness is decreased is 20 &#x3bc;m or more.

Interlayer for laminated glass, and laminated glass

There is provided an interlayer film for laminated glass capable of being enhanced in handling properties at the time of preparing laminated glass. The interlayer film for laminated glass according to the present invention has one end and the other end being at the opposite side of the one end, the thickness of the other end is larger than the thickness of the one end, and the glossiness on the surface of a maximum thickness part is 3% or more.

Interlayer for laminated glass, roll body, and laminated glass

There is provided an interlayer film for laminated glass capable of being enhanced in handling properties at the time of preparing laminated glass. The interlayer film for laminated glass according to the present invention has one end and the other end being at the opposite side of the one end, has two or more uniform thickness parts where the thickness is uniform in a direction connecting the one end and the other end, and has one or more thickness increasing part where the thickness is made to increase in the direction connecting the one end and the other end, the thickness of the other end is larger than the thickness of the one end, and the thickness in the uniform thickness part positioned nearest to the other end side is larger than the thickness in the uniform thickness part positioned nearest to the one end side.

Interlayer film for laminated glass, roll, and laminated glass

The present invention aims to provide an interlayer film for a laminated glass, which includes two or more stacked resin layers including a colored layer, exhibits excellent deaeration properties in a production process of a laminated glass, and is capable of preventing poor appearance of a colored portion, and a laminated glass including the interlayer film for a laminated glass. The present invention relates to an interlayer film for a laminated glass, having a laminated structure including two or more layers, at least including: an outer layer disposed on the outermost surface of the interlayer film for a laminated glass and having a large number of recesses on one surface; and a colored layer containing a colorant, a minimum distance between an outer layer side surface of the colored layer and the surface having a large number of recesses of the outer layer being 150 &#x3bc;m or longer.

Interlayer for laminated glass and laminated glass

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): 

Intermediate film for laminated glass and laminated glass

An interlayer film for a laminated glass providing excellent overall sound insulation at temperatures in the range of from 10 to 60&#xb0; C., which includes, a sound insulation layer 1; a middle layer; and a sound insulation layer 2, the layers each containing a polyvinyl acetal resin and a plasticizer and being laminated in the stated order, wherein the amount of the plasticizer per 100 parts by weight of the polyvinyl acetal resin in sound insulation layer 1 is different by from 5 to 60 parts by weight from the amount of the plasticizer per 100 parts by weight of the polyvinyl acetal resin in sound insulation layer 2, and the amounts of acetyl groups in the polyvinyl acetal resin contained in sound insulation layer 1 and sound insulation layer 2 each are larger than the amount of acetyl groups in the polyvinyl acetal resin contained in the middle layer.
