摘要:
An inkjet ink includes a pigment incorporated in an aqueous ink vehicle. The pigment includes metal oxide and/or mixed metal oxide particles and a plurality of reacted dispersant molecules attached to the outer surfaces of the particles to form a coating on the outer surfaces. The reacted dispersant molecules are attached to the metal oxide and/or mixed metal oxide particle outer surfaces through a silanol linking group of the reacted dispersant molecules. The coating is present in an amount ranging from about 10 wt % to about 50 wt % with respect to the wt % of the metal oxide and/or mixed metal oxide particles.
摘要:
A method for producing printed articles that encompasses providing a first ink composition that contains metal oxide particles with an average particle size in the range of about 3 to about 300 nm; providing a second ink composition that contains colored pigments dispersed in an ink vehicle; providing a printable media having a bottom supporting substrate and an ink-absorbing layer with pore diameters that are smaller than the size of the metal oxide pigment particles and colored pigments; and sequentially applying, on the same print area, the first and the second ink compositions onto said printable media. Also disclosed herein are the printed articles obtained according to the present method.
摘要:
A printed article with metallic appearance that includes a printable media on which a printed feature is formed with an ink composition. Said ink composition contains a dispersion of metal or metal oxide particles having an average particle size in the range of about 3 to about 180 nm. The media is a textured printable media containing a supporting substrate and an ink-absorbing layer with pore diameters that are smaller than the size of the metal or metal oxide particles. Said ink composition forms, onto the textured printable media, a printed feature that exhibits a metallic appearance.

Compositions and systems for production of color images with a fluoran leuco dye having a latent developer are disclosed and described. A color forming composition or composite can include a polymer matrix, a thermally modifiable fluoran leuco dye having a latent developer attached thereto, and a radiation absorber. The thermally modifiable fluoran leuco dye can be developable upon the color forming composition being contacted with electromagnetic radiation which causes the radiation absorber to become energized, so that the energized radiation absorber causes the latent developer to undergo rearrangement to produce an intermediate dye form having a phenolic substituent. The intermediate dye can then undergo an acid catalyzed ring opening to produce a colored dye form.

Chemical compositions are disclosed. One exemplary composition, among others, includes: a basic component, an acidic component, at least one acrylate component, oxidizing agent, reducing agent, and a binder. The binder includes a viscosity modifier and a surface tension modifier. The binder is capable of stimulating a reaction between the basic component and the acidic component. A portion of the binder is capable of undergoing a polymerization reaction between at least one acrylate component, the oxidizing agent, and the reducing agent. The polymerization reaction being initiated by the redox reaction between the oxidizing agent and the reducing agent.
