A manufacturing method for decorating natural leather with a decorative image includes applying on a crusted leather a base coat containing a pigment for providing a chromatic colour or an achromatic colour different from black, inkjet printing a colour image on the base coat using one or more pigmented UV curable inkjet inks, optionally applying a protective top coat on the image, and optionally applying a heat pressing or embossing step, wherein the chromatic colour or the achromatic colour different from black of the base coat and the inkjet printed colour image are used in combination to provide the decorative image.

Water based, energy curable ink jet compositions that have good insulating properties are described herein. The inventive water based energy curable ink jet compositions include a water soluble or water dispersible component polymerizable by free radical polymeration upon exposure to polymerizing radiation, wherein the cured ink jet compositions have good insulating properties, exhibited for example, by its breakdown voltage. Also described are electronic devices including ink jet-printed layers of the ink jet compositions.

A photopolymerizable composition comprises at least a polymerizable resin, a photosensitizer, an annihilator, and a photoinitiator. The photosensitizer is formulated to absorb an excitation light signal received in a first range of wavelengths. The annihilator is formulated to emit a light signal in a second range of wavelengths different from the first. During the absorption of light by the photosensitizer in the first range of wavelengths, the annihilator emits a light signal in the second range, a photon energy of the emitted light signal being greater than a photon energy of the light signal received by the photosensitizer. The annihilator is also formulated to implement an energy transfer mechanism to excite the photoinitiator for polymerization of the resin. The excited photoinitiator is formulated to generate at least one polymerizable initiator to cause the polymerization reaction. Related methods, such as three-dimensional printing methods, and materials are also disclosed.
