In one aspect, inks for use with a three-dimensional printing system are described herein. In some embodiments, an ink described herein is a composite ink. Such a composite ink, in some cases, comprises an optically transparent or substantially transparent carrier ink comprising a curable material; and a colorant dispersed in the carrier ink in an amount of about 0.01 to 5 weight %, based on the total weight of the composite ink.

Inks for 3D printing

The present disclosure provides an encapsulated dye dispersion and an inkjet ink comprising an ink vehicle and an encapsulated dye dispersion thereof. In particular, the encapsulated dye dispersion includes a fluorescent and/or photochromic dye. The present disclosure also provides a process for producing the encapsulated dye dispersion.

Encapsulated fluorescent and photochromic dye polyurethane dispersion

The present disclosure provides an encapsulated visible light absorbing dye dispersion, and the process for producing the same. The present disclosure further provides an inkjet ink comprising an ink vehicle and an encapsulated visible light absorbing dye dispersion thereof, and the process for producing the same.

Encapsulated visible light absorbing dye polyurethane dispersion

A phase change ink formulation comprising an ink base, carbon black pigment and a poly(hydroxystearic acid) derived dispersant.

Carbon black pigmented solid phase change ink formulations

Disclosed are colorants comprising a colored laked complex of (a) a chromogen molecule having at least one (i) carboxylic acid group, (ii) carboxylate group, (iii) sulfonic acid group, (iv) sulfonate group, or (v) combination thereof, and (b) a polymer, said chromogen molecule and said polymer each being complexed to (c) a metal. Also disclosed are phase change inks containing the colorants.

Colorants

Disclosed herein are ink compositions including an ink vehicle and a colorant, wherein the ink vehicle includes a compound having a formula of R&#x2014;CONH&#x2014;Ror R&#x2014;CONH&#x2014;R, wherein Ris a methyl group and Ris an alkyl group having from about 3 carbon atoms to about 200 carbon atoms.

Compounds suitable for use in inks and inks having such compounds

Disclosed herein are ink compositions including an ink vehicle and a colorant, wherein the ink vehicle includes a compound having a formula of R&#x2014;CONH&#x2014;Ror R&#x2014;CONH&#x2014;R, wherein Ris an alkyl group having from 1 to about 18 carbon atoms and Ris an alkyl group having from about 3 carbon atoms to about 200 carbon atoms, wherein Rand Rhave the same number of carbon atoms or Rhas less carbon atoms than R, and wherein at least one of the alkyl groups for Rand Rincludes at least one hydroxyl group substituent.

Disclosed herein are ink compositions including an ink vehicle and a colorant, wherein the ink vehicle comprises a compound having a formula of:
