Laminated body and its manufacturing method

Abstract

The following laminate exhibits weather resistance equal to or higher than that of a laminate having a plurality of thermally cured films as intermediate layers despite having a single intermediate layer composed of an active energy ray cured film between the organic resin base material and the inorganic vapor-deposited layer , Adhesion: It has an organic resin base material and a single-layer active energy ray-curable resin layer (i) and an inorganic vapor-deposited layer (ii) sequentially laminated thereon, and the reflectivity of the layer (i) is determined using the reflectance spectroscopy method. The obtained reflection spectrum is Fourier transformed for the wave number, and the threshold L of the power spectrum obtained by plotting the amplitude for the length dimension in the length dimension 0 L above 1 and L 2 , respectively have the first maximum value S 1 and the second maximum S 2 , the L 0 Set to 1×10 ‑6 ~3×10 ‑6 Any value of m, in addition to L 0 In the domain of definition of the power spectrum outside the following range, the first maximum value S 1 Shows a signal-to-noise ratio S of 5 or more relative to noise N 1 / N, the second maximum value S 2 Shows a signal-to-noise ratio S of 2 or more relative to noise N 2 / N.

Description

technical field [0001] The present invention relates to a laminate and a method for producing the same. More specifically, it relates to a laminate in which an active energy ray-curable resin layer and an inorganic vapor-deposited layer are laminated on an organic resin substrate and a method for producing the same. Background technique [0002] The laminate obtained by providing the inorganic vapor-deposited layer on the organic resin substrate has excellent processability and lightness derived from the organic resin, and excellent scratch resistance and chemical resistance derived from the inorganic vapor-deposited layer. Therefore, it has attracted attention as a glass substitute material. [0003] In addition, in such a laminated body, for the purpose of supplementing the weather resistance of the organic resin base material, the purpose of improving the adhesion between the organic resin base material and the inorganic vapor-deposited layer, etc., generally, the organic...

Problems solved by technology

[0012] On the other hand, when the thin film is a single layer and does not have birefringence (for example, the thin films of Patent Documents 2 and 4), it is considered that there are generally no multiple maximum values, and it is considered that multiple maximum values ​​are found. It is also caused by the vibration of the measurement object and the error of FFT processing

[0013] Therefore, although the power spectrum obtained by Fourier transforming the reflection spectrum of the film has been used in the measurement of film thickness, the physical interpretation related to the splitting of the power spectrum is limited, and the splitting of the power spectrum and the degree of splitting are called stacking. Useful metrics for analyzing the properties of volumes are unknown so far, and such utilization has not yet been made
