摘要:
Aqueous pigment ink and organic pigment powder are used for ink-jet recording to form high quality images. Organic pigment powder is prepared by finely granulating an organic pigment containing anthraquinone as principal ingredient by means of a vapor phase method to such an extent that the produced powder shows a number average particle diameter of primary particles of 10 to 50 nm. An aqueous ink contains such organic pigment powder.
摘要:
An ink comprises a recording agent and a liquid medium for dissolving or dispersing the recording agent, the ink comprising a compound represented by the general formula (I) or (II): ##STR1## where R.sub.1 and R.sub.2 are independently selected from the group consisting of radicals of hydrogen, alkyl or alkoxy having not more than 10 carbons, sulfonic acid or salts thereof, nitro, hydroxyl, carboxyl, and amino or derivatives thereof, and R.sub.1 and R.sub.2 are not simultaneously hydrogen radical. The ink is suitable used for ink-jet recording.
