Abstract:
Provided is an interlayer film for laminated glass capable of preventing generation of a void in the interlayer film in an end part of laminated glass. The interlayer film for laminated glass according to the present invention has a lengthwise direction and a widthwise direction, and includes the following configuration A, the configuration B or the configuration C.
Configuration A: containing a light stabilizer, and having such a distribution in content of the light stabilizer in the widthwise direction that the content of the light stabilizer is larger in one end side of the widthwise direction.
Configuration B: containing an ultraviolet ray screening agent, and having such a distribution in content of the ultraviolet ray screening agent in the widthwise direction that the content of the ultraviolet ray screening agent is larger in one end side of the widthwise direction.
Configuration C: containing an oxidation inhibitor, and having such a distribution in content of the oxidation inhibitor in the widthwise direction that the content of the oxidation inhibitor is larger in one end side of the widthwise direction.
Configuration A: containing a light stabilizer, and having such a distribution in content of the light stabilizer in the widthwise direction that the content of the light stabilizer is larger in one end side of the widthwise direction.
Configuration B: containing an ultraviolet ray screening agent, and having such a distribution in content of the ultraviolet ray screening agent in the widthwise direction that the content of the ultraviolet ray screening agent is larger in one end side of the widthwise direction.
Configuration C: containing an oxidation inhibitor, and having such a distribution in content of the oxidation inhibitor in the widthwise direction that the content of the oxidation inhibitor is larger in one end side of the widthwise direction.
