Abstract:
Provided is an inkjet composition for printing an indelible colorant onto a substrate. Also provided is a method of printing using the inkjet composition, and a printed substrate obtainable and obtained from the method of printing. The inkjet composition has an indelible colorant, one or more solvents, and a binder. The migration distance of the indelible colorant in the substrate is less than 0.85 mm after 7 days at 25 °C. The composition may be used to provide indelible markings in the surface of the substrate, and these markings do not significantly disperse over time.
Abstract:
In one aspect, inks for use with a three-dimensional (3 D) printing system are described herein. In some embodiments, an ink described herein comprises up to 80 wt. % oligomeric curable material; up to 80 wt. % monomeric curable material; up to 10 wt. % photoinitiator; up to 1 wt. % non-curable absorber material; and up to 10 wt. % one or more additional components, based on the total weight of the ink, and wherein the total amount of the foregoing components is equal to 100 wt. %. Additionally, the photoinitiator is operable to initiate curing of the oligomeric curable material and/or the monomeric curable material when the photoinitiator is exposed to incident curing radiation having a peak wavelength λ. Moreover, the ink has a penetration depth (D p ), a critical energy (E c ), and a print through depth (D PT ) at the wavelength λ of less than or equal to 2 x D p .
Abstract:
A shell (100) is provided. The shell (100) includes a metallic body (10), a non-metallic layer (20) and a coating layer (30). The metallic body (10) has a first part and a second part separated from the first part. The non-metallic layer (20) is configured to connect the first part and the second part of the metallic body (10), and the coating layer (30) is on an outer surface of the non-metallic layer, and has a consistent appearance with the metallic body (10). A method for manufacturing the shell (100) and the mobile terminal (200) including the shell (100) are also provided.
Abstract:
Provided is an ink set including at least two inks each including a coloring material, an organic solvent, and water, wherein a proportion of the organic solvent in each of the inks is 30 percent by mass or greater, wherein a relative mobility difference (maximum relative mobility-minimum relative mobility) between a maximum relative mobility and a minimum relative mobility among relative mobilities of the coloring materials included in the inks is 0.1 or greater, where the relative mobilities are obtained by thin-layer chromatography in which the coloring materials are developed using the organic solvents included in the inks as developing solvents.
