A method of inkjet printing includes ink jetting an aqueous inkjet ink composition to form a white printed image on a substrate. The aqueous inkjet ink composition comprises particles of titanium dioxide that are present in an amount of at least 4 to 15 weight % and the particles have a 95percentile particle size of less than 200 nm and a 50percentile particle size of less than 130 nm. The titanium dioxide particles are dispersed within the aqueous inkjet ink composition using a dispersing polymer that is a styrene-(meth)acrylic acid polymer, styrene-maleic anhydride polymer, or styrene-maleic acid polymer and the weight ratio of the titanium dioxide particles to the dispersing polymer is from 19:1 to and including 2:1.

Method for ink jetting opaque ink composition

An aqueous dispersion contains pigment colorant particles that are present in an amount of at least 5 weight % and up to and including 80 weight %; a dispersing polymer that is a hexyloxy benzoic acid polymer; and an aqueous medium. The weight ratio of the pigment colorant particles to the dispersing polymer is from 19:1 to and including 2:1. Such aqueous dispersions can be incorporated into aqueous inkjet ink compositions that can be used for forming opaque images such as white images using inkjet printing methods.

Pigment dispersions and inkjet ink compositions

Inkjet printing is carried out on a substrate having a topmost layer comprising aqueous soluble multivalent metal cations and a hydrophilic polymeric binder. An aqueous inkjet ink composition is drawn from a main fluid supply as a continuous stream that is broken into both printing drops and non-printing drops, forming a white printed image on the substrate with the printing drops. The non-printing drops are collected and returned to the main fluid supply. The aqueous inkjet ink composition comprises particles of titanium dioxide in an amount of at least 4 to 15 weight %. The particles of titanium dioxide have a 95percentile particle size of less than 200 nm, a 50percentile particle size of less than 130 nm, and are dispersed using a dispersing polymer comprising acidic groups. The weight ratio of the particles of titanium dioxide to the dispersing polymer is 19:1 to 2:1.

Providing opaque ink jetted image

An aqueous dispersion contains pigment colorant particles (of various types of materials) at 5 weight % and up to and including 80 weight %; a dispersing polymer that is prepared from the Diels Alder adduct of 3-maleimidopropionic acid and furfuryl (meth)acrylate; and an aqueous medium. The weight ratio of the pigment colorant particles to the dispersing polymer is from 19:1 to and including 2:1. This aqueous dispersion can be incorporated into an aqueous inkjet ink composition that can be used in various inkjet printing methods to provide opaque images particularly when titanium dioxide particles are used as the pigment colorant.

Aqueous colorant dispersions and inkjet compositions

A first polymer latex and second polymer latex can be mixed to form a dried primer layer on a substrate to adhere patterned materials having fine lines. The first polymer latex comprises a first polymer and a first surfactant such that a dried coating of the first polymer latex has a surface polarity of at least 50%. The second polymer latex comprises a second polymer and a second surfactant such that a dried coating of the second polymer latex has a surface polarity of less than or equal to 27%. Moreover, a dried coating of the mixture has a surface polarity of at least 15% and up to and including 50%. Primed substrates are useful for preparing electrically-conductive articles having electrically-conductive fine lines directly on a dried primer layer by applying a patterned material to a substrate. Such articles can be used as touch screen displays in various electronic devices.
