Provided are novel ink formulations based on metal salts and metal complexes. The formulations include a sole metal precursor in the form of metal salt nanoparticles dispersed in a medium. In addition, the metal salt nanoparticles may include an anion. The novel ink formulations may be used for producing conducting patterns.

One or more implementations of a multi-layer film include a first substantially un-pigmented layer non-continuously bonded to a second pigmented layer. The multi-layer film includes an unexpected appearance differing from the appearance of the pigmented layer. In one or more embodiments, the multi-layer film includes a metallic appearance despite the pigmented layer being devoid of metallic pigment. The multi-layer film also includes areas that are visually distinct from areas of the film with the unexpected appearance. The visually-distinct areas comprise areas in which the first substantially un-pigmented layer non-continuously bonded is in intimate contact with the second pigmented layer. The visually-distinct areas have the appearance of the pigmented layer. One or more implementations also include methods of making multi-layer films and bags with an unexpected appearance and visually-distinct areas.

The present disclosure relates to a decorative panel made of flat glass for electronic household appliances, in particular, for large stationary household appliances. The decorative panel comprises a base body made of thermally tempered flat glass with an operational front and an operational back, and has at least one digital print on the operational back.

An ink jet composition of the invention is discharged by an ink jet method and includes: metal powder; an organic solvent; and a resin having a styrene-maleic acid structure as a binder resin, in which the ink jet composition contains metal powder surface-treated with a fluorine-based compound as the metal powder.

Techniques, systems, devices and materials are disclosed for spectrally selective coatings for optical surfaces having high solar absorptivity, low infrared emissivity, and strong durability at elevated temperatures. In one aspect, a spectrally selective coating includes a substrate formed of a light absorbing material, and a composite material formed over the substrate and including nanoparticles dispersed in a dielectric material, in which the composite material forms a coating capable of absorbing solar energy in a selected spectrum and reflecting the solar energy in another selected spectrum.

The present invention relates to a composition for forming a conductive pattern that enables forming conductive micropatterns on various polymer resin products or resin layers by a simplified process without deformation of the polymer resin products or resin layers, and enables effectively satisfying requirements of the art, and a resin structure having a conductive pattern.

A protective cover for use with an electronic device includes a protective shell, an electrical connector, and an inductive coil. The protective shell is configured to receive the electronic device and includes one or more apertures configured for accessing one or more respective features of the installed electronic device. The electrical connector is affixed to an interior surface of the protective shell and configured to engage electrical contacts of the installed electronic device. The inductive coil is disposed within the protective shell and is electrically connected to the electrical connector of the protective shell. The inductive coil is configured for producing an electrical current in response to a magnetic field generated by an external device in proximity to the protective shell.
