Abstract

A composite ink for ink-jet printer contains at least one black pigment and a medium (secondary alcohol ethoxylate). Its advantages are optimal print quality, good optical density, high resistance towater and friction, and not blocking nozzle.

Description

technical field [0001] The invention relates to an ink composition, in particular to a black ink composition applied to an inkjet printer. Background technique [0002] With the gradual development of personal computers, ink jet printers have become very common interface devices, widely used in homes, personal studios, and even in various industries. The main advantages of inkjet printers are low price, low noise during operation, and excellent full-color printing quality, and can be printed on various media, such as plain paper, special inkjet printing paper (coating paper), photo paper (photo paper), and special slides (transparence), etc. [0003] Good inkjet ink, when printed on the inkjet carrier, there will be no ink blocking the ink nozzle, and the printing quality after the ink contacts the carrier is good, for example, no bleeding and feathering will occur ( feathering), with high optical density (optical density), good wear resistance (smearing), water fastness (...
