  • Patent number: 11960182
    Abstract: Provided is a light absorption anisotropic film capable of preparing an image display device having excellent display performance and excellent durability, and a laminate and an image display device formed of the light absorption anisotropic film. The light absorption anisotropic film is used for an image display device, which is formed of a liquid crystal composition containing a liquid crystal compound and a dichroic substance, in which in a signal derived from the dichroic substance detected by time-of-flight secondary ion mass spectrometry, a relationship between a maximum intensity Imax of the light absorption anisotropic film in a thickness direction and an intensity Isur1 in a surface of the light absorption anisotropic film on a viewing side of the image display device satisfies Expression (I-1) 2.0?Imax/Isur1.
    Type: Grant

  • Patent number: 10654005
    Abstract: The method for producing a gas separation composite membrane includes applying a mixed liquid containing compounds (a) and (b) below onto a porous support to form a coating film and curing the coating film to form a crosslinked polysiloxane compound layer: (a) a particular crosslinkable polysiloxane compound having a structural unit (a1), a structural unit (a2), and a structural unit (a3) or (a4), and (b) a particular crosslinkable polysiloxane compound having a structural unit (b1), a structural unit (b2), and a structural unit (b3) or (b4), where R1a to R1f and R2a to R2f represent a particular group and * represents a particular linking site.
