Embodiment 1 and 2

[0052] Formulation of Phase Change Inks of Embodiments of the Invention

[0053] Colorants (naphthol blue-black, nitrazine yellow) and N,N-dimethyldioctadecyl bromide (N,N-dimethyldioctadecyl bromide) are commercially available from Sigma Aldrich. The modified naphthol blue-black and nitrazine yellow compounds can be obtained by combining a commercially available colorant with N, N-dimethylbis(octadecyl) bromide and colorant p-ammonium bromide 1: 2 ratio for the reaction to prepare. The reaction proceeded very rapidly in water at 80°C and the resulting insoluble compound was isolated by filtration using a glass frit.

Abstract

A phase change ink compositions, comprising a novel colorant wax to prevent and / or reduce printhead and nozzle contamination in ink jet printers caused by drooling and faceplate staining. In particular, there is provided novel colorants containing acid groups for use in phase change ink compositions and which are compatible with phase change ink components.

Description

technical field [0001] The present embodiments relate generally to phase change ink compositions, and, more particularly, to acid colorants for use in phase change ink compositions to prevent and / or reduce spraying caused by drooling and panel staining. Contamination of printheads and nozzles in ink printers. Phase change inks or solid ink compositions are characterized by being solid at room temperature and melting at elevated temperatures at which point the molten ink is applied to the substrate. These phase change ink compositions generally include an ink vehicle and a colorant, and can be used in inkjet printing. Background technique [0002] Phase change or solid ink printers typically receive ink in a solid form, sometimes referred to as an ink stick. Ink sticks are typically inserted through an insertion opening of the printer's ink loader and moved towards the heated plate by a feed mechanism and / or gravity. The heated plate melts the phase change ink in contact w...
