The present disclosure is drawn to a composite particulate build material, including 92 wt % to 99.5 wt % polymeric particles having an average size from 10 μm to 150 μm and an average aspect ratio of less than 2:1. The composite particulate build material further includes from 0.5 wt % to 8 wt % reinforcing particles having an average size of 0.1 μm to 20 μm and an average aspect ratio of 3:1 to 100:1 applied to a surface of the polymeric particles.

An example of a liquid ink includes a pigment dispersion, a polyurethane dispersion, a polytetrafluoroethylene wax emulsion, a co-solvent, and a balance of water. A particle diameter of a polytetrafluoroethylene wax in the polytetrafluoroethylene wax emulsion is less than 50 nm. Examples of the liquid ink may be incorporated into a thermal inkjet printing system.

A process for producing a three-dimensional object by selectively layer-by-layer solidification of a powdery material layer at the locations corresponding to the cross-section of the object in a respective layer by exposure to electromagnetic radiation. The powdery material comprises at least one polymer which is obtainable from its melt only in substantially amorphous or completely amorphous form, or a polyblend which is obtainable from its melt only in substantially amorphous or completely amorphous form. The powdery material has a specific melting enthalpy of at least 1 J/g.

Described are primer coatings, overprint varnishes, and seaming solution solutions for application to substrates such as those used to make wrap around and sleeve labels, particularly shrink wrap labels, which are used to label containers. The labels can be digitally printed with or without lane priming. With certain seaming solutions, the labels can be removed in the wash stage to enable the recycling of containers.

An object is to obtain an electron beam-curable printing ink composition that maintains such basic properties as curability, adhesion, scratch resistance, etc., without containing any traditional polymerization initiator. As a solution, an electron beam-curable printing ink composition is provided that contains dimethylpolysiloxane by 0.1 to 3.5% by mass relative to the total composition.
