    Abstract: A multi-phase latex particle composition includes at least two different heteropolymers defining at least two different phases. The heteropolymers are selected such that a cumulative percentage of i) any heteropolymers including less than 30% of a C6 or greater (meth)acrylate monomer ranges from about 20 wt % to about 80 wt % of a total particle composition weight; ii) any heteropolymers having a glass transition temperature (Tg) ranging from 15° C. to 75° C. ranges from about 20 wt % to about 70 wt % of the total weight; iii) any heteropolymers having a Tg greater than 75° C. is greater than 30 wt % of the total weight; iv) any heteropolymers having a Tg less than 15° C. is less than 20 wt % of the total weight; and v) an aromatic group monomer is less than 10 wt % of the total weight.

    Abstract: The present disclosure refers to an inkjet ink set comprising a black ink with a black pigment, a yellow ink with a yellow pigment, a cyan ink with a cyan pigment, a magenta ink with a magenta pigment and a white ink with a white pigment. At least one of the ink further contains a latex binder that is dispersed in the ink vehicle, and that includes a first heteropolymer including two or more aliphatic (meth)acrylate ester monomers or two or more aliphatic (meth)acrylamide monomers; and a second heteropolymer including a cycloaliphatic monomer and an aromatic monomer. The present disclosure refers also to a printing method using the ink set and to a system for printing the ink set.

    Abstract: The present disclosure provides a white ink comprising an aqueous ink vehicle, a white colorant, and latex particles. The colorant can consist essentially of metal oxide particles present at from 2 wt % to 50 wt %, can have an average particle size from 100 nm to 1000 nm, and can have a high refractive index from 1.8 to 2.8. The latex can be present in the ink at from 2 wt % to 20 wt %, can have a glass transition temperature from 0° C. to 130° C., and can have a low refractive index from 1.3 to 1.6. The metal oxide particles and latex particles can be present in the white ink at weight ratio is from 6:1 to 1:3.

    Abstract: The present disclosure provides ink-jet inks incorporating dimeric fluorosurfactants. As such, an ink-jet ink can include a liquid vehicle; a non-ionic fluorosurfactant dimer having the structure CF3(CF2)x(CH2)y(CR2CR2O)z-A-(OCR2CR2)a(CH2)b(CF2)cCF3, where R is independently H or methyl, A is a bridging unit containing aliphatic or aromatic functionality, x is 3 to 18, y is 0 to 8, z is 0 to 100, a is 0 to 100, b is 0 to 8, and c is 3 to 18; and a polymer.
