摘要:
An ink set for recording a color image with inks of two or more colors including at least one black ink and one color ink on a recording medium is provided. The ink set includes a black ink containing a self-dispersible carbon black having at least one cationic group bonded directly or through another atomic group to the surface thereof, and a color ink containing an anionic substance and having a buffering capability against a pH change. The ink set satisfies the requirements for print quality, image durability, and so forth and does not cause bleeding between a black ink-printed area and a color ink-printed area.
摘要:
Disclosed herein is an ink comprising a first pigment, a second pigment and a dispersant, both of the pigment being dispersed in an aqueous medium, wherein the first pigment is a self-dispersing pigment having an anionic group or a cationic group, the group being bonded directly or through an atomic group to a surface of the pigment, the second pigment is a pigment dispersible in an aqueous medium with the dispersant, and the dispersant is an ionic polymeric dispersant having a same polarity as that of the group bonded to the surface of the pigment or a nonionic polymeric dispersant.
摘要:
Provided is a black ink capable of mitigating the dependency on image quality of recording media and giving a high quality image stably, which comprises at least one salt selected from the group consisting of (M1)2SO4, CH3COO(M1), Ph_COO(M1), (M1)NO3, (M1)Cl, (M1)Br, (M1)I, (M1)2SO3 and (M1)2CO3, where M1 is an alkali metal, ammonium or organo-ammonium and Ph is a phenyl group, and a self dispersible carbon black.

摘要:
Thermal transfer recording is improved by a recording method involving providing a thermal transfer material having a support and an ink layer disposed thereon and which in turn includes a binder and a colorant. The binder includes 45-70 wt. % of an ethylene-vinyl acetate copolymer, 25-50 wt. % of a wax, and 7-12 wt. % of a tackifier based on a total weight of the binder. The ink layer has a breakdown strength of 30-80 kg/cm.sup.2 at 25.degree. C. The method also involves contacting an ink layer side of the thermal transfer material with a recording medium, supplying a pattern of energy from a recording head to the thermal transfer material, and separating the thermal transfer material from the recording medium to leave a transferred image on the recording medium. The thermal transfer material moves in a unit period of time by a first distance relative to the recording head which is smaller than a second distance through which the recording medium moves relative to the recording head in the same unit period of time.
