    Abstract: A decorative structure (20) comprising a planar support (22) and a faceted microstructure (24) on at least one side of the planar support (22) is provided. The decorative structure (20) may further comprise an at least partially reflective layer (26) configured to at least partially reflect light that passes through the microstructure (24). The faceted microstructure (24) comprises a plurality of grooves (28) creating a pattern of facets (30) over the surface of the support (22), such that the microstructure (24) is capable of splitting incident light into spectral colours. In embodiments, the grooves (28) have a triangular or V-shaped profile. Methods of making a decorative structure(20) and articles incorporating the decorative structure (20) are also described.

    Abstract: 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.
