Embodiment 1

[0185] The laminate of Example 1 will be described.

[0186]

[0187] As a metal substrate, an aluminum foil (manufactured by UACJ Corporation, alloy number 1N30, thickness 9 μm) having a size of 100 mm square was prepared. Then, two liquid curable polyurethane-based binders (manufactured by SANYUREC.LTD., SU3600A and SU3600B) were weighed so that the mass ratio was 30:100, and these were dissolved in ethyl acetate to prepare a solid content concentration of 30% by mass. The adhesive layer coating solution.

[0188] The adhesive layer coating liquid was applied on the above-mentioned aluminum foil, and a 100 mm square PET film (TOYOBO CO., LTD., COMOSSHINE (registered trademark) A4100 (one-side easy-adhesion) PET film with a thickness of 125 μm constituting the resin layer was attached. layer), thickness 125 μm). The drying temperature was set at a temperature of 70° C., and the composite material of the aluminum foil and the resin layer was produced by curing it for a dry...

Embodiment 2

[0202] In Example 2, compared with Example 1, the immersion time in the alkali etching process of the composite of an aluminum foil and a resin layer was made into 35 second, and it was the same as Example 1 except that.

Embodiment 3

[0204] In Example 3, compared with Example 1, the immersion time in the alkali etching process of the composite of an aluminum foil and a resin layer was made into 30 second, and it was the same as Example 1 except that.

Abstract

Provided is a laminate in which excellent viewability is achieved by improving imaging blur. This laminate has: a metal substrate provided with a plurality of through-holes passing therethrough in thethickness direction; and a resin layer provided on at least one surface of the metal substrate. When the average opening ratio of the through-holes is G%, and the opening ratio of the through-holes having an opening diameter of no greater than 100 [mu]m is H%, the average opening ratio G% satisfies 50%<= average opening ratio G%<=80%, and the ratio R represented by the opening ratio H% / the average opening ratio G% satisfies 0.0001<=R<=0.5

Description

technical field [0001] The present invention relates to a laminate having a metal base material provided with a plurality of through holes penetrating in the thickness direction, and a resin layer provided on at least one surface of the metal base material, and in particular, to an average opening that defines the through holes A laminate having an aperture ratio of through-holes having an aperture diameter of 100 μm or less. Background technique [0002] Conventionally, there has been proposed an optical film that is disposed on an object to limit the field of view or improve light transmittance. [0003] Patent Document 1 describes a light-transmitting optical film having a low-refractive-index layer and a high-refractive-index layer inside a thin film which are perpendicular to and parallel to each other and alternately and continuously at predetermined intervals. In the optical film of Patent Document 1, with respect to the light incident on the optical film, the direct...
