consumed computer accessories. SUBSTANCE: solid ink composition is designed to apply from melt and contains medium with conductivity at least 108 Ohm.cm, dispersed therein particles of insoluble coloring mater, and substance conferring charge to these particles. Coloring particles may be represented by pigment, insoluble dye, polymer, or their mixture. Charge-conferring substance may be represented by fatty acid metal salt, fatty acid, lecithin, organophosphorus compound, succinimide, sulfosucinate, petroleum sulfonates, soluble or partially soluble resin such as modified colophony ester, acrylic resin, vinyl resin, hydrocarbon resin, or their mixtures. Ink can additionally contain viscosity-control substance and be heated to 155 C to reach viscosity between 5 and 150 cPs. EFFECT: increased resolution and optical density of image when light- and water-resistant pigments are employed. 24 cl, 14 ex
