  An object is to provide a polyvinyl acetal film which has excellent transparency and can suppress a thermal cracking phenomenon. The above object is achieved by providing a polyvinyl acetal film in which a ratio between a composite modulus (GPa) of the highest part in a convex part and a composite modulus (GPa) of the lowest part in a concave part on a surface of a film on a side in contact with glass, calculated by a nanoindentation measurement using a scanning probe microscope, is 0.90 or less, when a laminated glass is formed. In addition, the above object is achieved by providing a polyvinyl acetal film in which a ratio between a hardness (GPa) of the highest part in the convex part and a hardness (GPa) of the lowest part in the concave part, calculated by the SPM nanoindentation measurement, is 0.90 or less.

  目的是提供一种聚乙烯醇缩醛薄膜，它具有优异的透明度，并能抑制热裂纹现象。 实现上述目的的方法是提供一种聚乙烯醇缩醛薄膜，当形成层压玻璃时，通过使用扫描探针显微镜进行纳米压痕测量，计算出薄膜与玻璃接触一侧表面上凸部最高部分的复合模量（GPa）与凹部最低部分的复合模量（GPa）之比为 0.90 或以下。此外，通过提供一种聚乙烯醇缩醛薄膜，其中通过 SPM 纳米压痕测量法计算出的凸面部分最高部分的硬度（GPa）与凹面部分最低部分的硬度（GPa）之比为 0.90 或更小，从而达到上述目的。

  A first object of the invention is to provide an interlayer film for laminated glass, which can brighten the entire room by suppressing reduction of the amount of solar light penetrating through a laminated glass and efficiently diffusing the penetrated light, and a laminated glass using the interlayer film. A second object of the invention is to provide a production method for recycling a trim or an out-of-specification product of an interlayer film for laminated glass, the interlayer film using a polyvinyl acetal resin layer and a thermoplastic elastomer layer, and thereby obtaining an interlayer film for laminated glass having secured light transmission properties and light scattering properties. The invention relates to an interlayer film for laminated glass having layer A containing a polyvinyl acetal resin, in which a thermoplastic elastomer is dispersed in layer A, and in the case of producing a laminated glass using the interlayer film, the laminated glass has a haze of 10% or higher and a total light transmittance of 80% or higher.

  本发明的第一个目的是提供一种夹层玻璃用中间膜，该中间膜可以通过抑制减少穿透夹层玻璃的太阳光量和有效漫射穿透的光线来照亮整个房间，并提供一种使用该中间膜的夹层玻璃。本发明的第二个目的是提供一种生产方法，用于回收夹层玻璃中间膜的边角料或不合规格产品，中间膜使用聚乙烯醇缩醛树脂层和热塑性弹性体层，从而获得具有可靠透光性能和光散射性能的夹层玻璃中间膜。 本发明涉及一种夹层玻璃用中间膜，其 A 层含有聚乙烯醇缩醛树脂，在 A 层中分散有热塑性弹性体，在使用该中间膜生产夹层玻璃的情况下，夹层玻璃的雾度为 10% 或更高，总透光率为 80% 或更高。

  The present invention is intended to provide a resin composition that gives a film having excellent transparency when molded. The present invention relates to a resin composition including 0.5 to 100 parts by mass of a thermoplastic polyolefinic resin (B) with respect to 100 parts by mass of a polyvinyl acetal resin (A), wherein when the resin composition is molded into a film having a thickness of 0.76 ± 0.03 mm and the film is laminated between two sheets of float glass having a thickness of 3 mm, the laminate has a haze of less than 5%. It is preferable that a phase of the thermoplastic polyolefinic resin (B) is dispersed as an island component in a continuous phase of the polyvinyl acetal resin (A).
