Derivative Assay:Article Title: Light absorption anisotropic film, laminate, and image display device
Article Snippet: .. The measurement by TOF-SIMS in the present invention is carried out as described below. (1) Device and Conditions Device: TRIFT V nanoTOF II (manufactured by Ulvac PHI Inc.) Depth direction analysis: analyzed in combination with an Ar ion sputter Measurement range: raster scanning of 256 points each in a direction and in orthogonal direction Polarity: positive or negative (2) Intensity Isur on Surface of Film In a case where a light absorption anisotropic film, which is a measurement target, is subjected to a mass spectrometric analysis measurement in a portion from each surface of the light absorption anisotropic film to 10% of the total thickness, among the average values (the average value of the intensity from the baseline) of the intensities of fragments derived from the dichroic substance, a lower value is defined as the intensity Isur. (3) Maximum Intensity Imax in Thickness Direction of Film In a case where a light absorption anisotropic film, which is a measurement target, is subjected to a mass spectrometric analysis measurement in a region to 80% of the total thickness, excluding the portion from each surface of the light absorption anisotropic film to 10% of the total thickness, the maximum value of the intensities (the intensity from the baseline) of fragments derived from the dichroic substance is defined as the maximum intensity Imax. (4) About Measurement Target In a case where a light absorption anisotropic film, which is a measurement target, is present as a laminate having an adjacent layer, the surface of the above-described light absorption anisotropic film (that is, the interface with the adjacent layer) can be identified as a point where the mass spectrometric intensity of the fragment derived from the high-molecular weight liquid crystal compound detected from the light absorption anisotropic film intersects with the mass spectrometric intensity of the fragment derived from the most abundant compound among the fragments detected from the adjacent layer. ..
