摘要： 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.-

摘要： The present invention aims to provide an interlayer film for a colored laminated glass which exhibits a visible light transmittance Tv of 5% or lower, small variation in visible light transmittance and an excellent appearance when incorporated in a laminated glass together with two clear glass plates in conformity with JIS R3202 (1996), and a colored laminated glass produced using the interlayer film for a colored laminated glass. Provided is an interlayer film for a colored laminated glass having, recesses on at least one surface, and exhibiting a visible light transmittance Tv of 5% or lower when incorporated in a laminated glass together with two clear glass plates in conformity with JIS R3202 (1996), the interlayer film for a colored laminated glass including a laminate of at least two layers including a first resin layer containing a thermoplastic resin and a colorant and a second resin layer containing a thermoplastic resin and no colorant, the elastic modulus E1 of the first resin layer and the elastic modulus B2 of the second resin layer having a ratio E1/E2 of 1.25 or more, the thickness t1 of the first resin layer and the thickness t2 of the second resin layer having a ratio t1/t2 of 2.0 or less.

摘要： Provided is laminated glass capable of preventing generation of a projection in the interlayer film in an end part of laminated glass, and keeping the appearance of laminated glass excellent. Laminated glass according to the present invention is laminate glass including a first lamination glass member, a second lamination glass member, and an interlayer film containing a thermoplastic resin, and when a light irradiation test: “conducting 4 cycles each cycle including the process of irradiating the laminated glass with xenon light at a black panel temperature of 83° C. and a humidity of 50% RH for 144 hours, and dipping the laminated glass in pure water at 80° C. for 24 hours” is conducted in the laminated glass, a ratio of a weight average molecular weight of the thermoplastic resin at a position of 2 mm inwardly from an end part of the laminated glass, to a weight average molecular weight of the thermoplastic resin at a position of 70 mm inwardly from an end part of the laminated glass is more than 0.5.
