Abstract: The present disclosure provides a decorative film including a base material and an optical reflective layer coloring by optical interference or structural color, in which at least two or more layers of the optical reflective layer are laminated, and diffuse reflectivities of the respective optical reflective layers are different from each other, or a printing layer is laminated between the respective optical reflective layers; a decorative molded article; a decorative panel; and an electronic device.

Abstract: A manufacturing method of a laminate includes: providing an optical mask layer on a substrate by printing a first pattern having AM screen tone with a screen ruling of 250 lines or less and having a halftone dotted region having a halftone dot area ratio of 0.5% to less than 99.5% on the substrate using a first ink, and printing a second pattern having a semi-translucent solid region having a print-area ratio of 99.5% or more and a light transmittance of 5% to less than 95% at a position overlapping the halftone dotted region of the first pattern using a second ink; providing a liquid crystal layer containing a liquid crystal compound and a photosensitive chiral agent on a side of the substrate opposite to the optical mask layer; and irradiating the liquid crystal layer with light through the optical mask layer to subject the photosensitive chiral agent to photoreaction.

Abstract: Provided are a decorative film including a base material and a reflective layer having a convex structure, in which, in a cross section obtained by cutting the convex structure in a direction perpendicular to a plane direction of the decorative film, in a case where a direction in which an average ΦAVE of positive tilt angles is a largest is defined as a first direction and a direction in which the average ΦAVE of the positive tilt angles is a smallest is defined as a second direction, the decorative film has a region A in which ΦAVE in the first direction is 3° or more and ΦAVE in the second direction is less than 3°; and applications thereof.
