A method may produce a ceramic part with a mother-of-pearl effect, in particular for watchmaking. Such methods may include: forming a ceramic body; depositing a layer of an oxy-nitride component of the OxNy type on at least a portion of the ceramic body; and oxidizing at least a portion of the oxy-nitride layer, preferably by heating.

The present invention relates to a process for the production of a pattern having a three-dimensional appearance in a coating comprising flake-form effect pigments, to a coating produced in this way, and to the use thereof.

An outer surface of a Decorative Product comprising an outer covering layer covering the outer surface, the outer covering layer comprises a UV ink coating layer and an outer protective layer disposed on a surface of the UV ink coating layer facing towards the exterior of the Decorative Product. The UV ink coating layer comprises a plurality of close-packed jewel-shaped elements and the surface of the UV ink coating layer comprises an elongated mesa-like protrusion having a substantially planar top face. The outer protective layer includes an amber varnish layer. The outer protective layer is configured to protect the appearance, color and brightness of the jewel-shaped element.

A method of producing preconfigured arrangements of mobile shape-designed particles. The method includes providing a composite structure comprising a substrate and a layer of particle material over a surface of the substrate; lithographically producing a plurality of shaped-designed particles from the layer of particle material such that the plurality of shaped-designed particles remain substantially in a layer proximate the substrate; and at least one of subsequent to or in conjunction with the lithographically producing, immersing the plurality of shaped-designed particles the substrate in a fluid material, at a preselected temperature. The fluid material comprises a depletion agent having particles having sizes and a volume fraction to provide depletion attraction between at least a portion of the shaped-designed particles and the substrate such that the shaped-designed particles remain substantially in the layer proximate the substrate.
