The printed article includes a medium having a specular reflective layer, a first line composed of a first color formed at the medium, a second line formed at the medium in a second color and formed parallel to the first line, and a prism layer formed onto at least the first line, wherein when the medium is divided into a first region, a second region, and a third region that are continuous in parallel, the first line is disposed in any one region of the first region, the second region, and the third region, the second line is disposed in any one region other than the region where the first line was formed, the prism layer is disposed across two contiguous regions including the region formed with the first line, and the section of the prism layer has a shape of a portion of the non-circular arc approximating the ellipse.

One or more aspects of the present disclosure are directed to bladders that incorporate a multi-layer optical film that impart a structural color to the bladder. The present disclosure is also directed to articles including the bladders having a multi-layer optical film, and methods for making articles and bladders having a multi-layer optical film.

A workpiece composed of acrylic material can be modified to produce a highly visual and aesthetic prismatic effect in which white light entering the workpiece can exit the workpiece in separate colors and sets. By applying dichroic paint and primer to precision cuts made into one of the planar surfaces of the workpiece, preferably filling in the spaces with a resin epoxy and then preferably sanding the surface, many more colors can be generated by the white light exiting the workpiece.

As described above, one or more aspects of the present disclosure provide articles having structural achromatic color, and methods of making articles having structural achromatic color. The present disclosure provides for articles that exhibit structural color upon exposure to white light (e.g., sunlight, artificial light, or a combination) that shifts based on the angle of observation and/or incident light. At least one shift in the structural color is between an achromatic structural color and a chromatic structural color. The shift occurs at different angles of observation and/or angle of incident light.

A transfer sheet is configured to include a base sheet; a releasable layer laminated on the base sheet, containing an ultraviolet curing resin, and including minute irregularities on at least part of a surface opposite to a surface in contact with the base sheet; a peeling layer laminated entirely on the releasable layer; and a single color solid print layer laminated in a section on the peeling layer corresponding at least to a region where the minute irregularities of the releasable layer are formed. A maximum width W of a recessed portion of the minute irregularities and a depth D of the recessed portion of the minute irregularities satisfy 10≤W/D≤50, W≤100 μm and 2 μm≤D≤10 μm. At least one of the number of recessed portions per unit area and the depth of the recessed portion changes stepwise.
