摘要:
An object of the invention is to provide an ink set which enables to improve image density and scratch resistance of the images recorded using an ink containing a self-dispersion pigment and an ink containing a modified siloxane compound. An ink set to be used for ink jet recording including plural inks having a first ink and a second ink independently, wherein the first ink contains at least a pigment having functional groups on surface of pigment particles and a compound having adsorptivity to the pigment and the functional group density on the surface of the pigment particles is 1.5 μmol/m2 or more and less than 2.6 μmol/m2 and the second ink contains at least a pigment and a modified siloxane compound.

摘要:
Provided is an ink jet ink capable of recording an image having an unprecedentedly high level of scratch resistance and excellent glossiness while satisfying reliability of the ink such as ejection stability. The ink jet ink contains at least a pigment and a graft polymer, and is characterized in that the graft polymer includes at least a specific nonionic unit and a unit having a polysiloxane structure.
摘要:
Provided are an ink jet ink set, an ink jet recording method, and an ink jet recording apparatus each of which can reduce the graininess of an image to be recorded and improve the water fastness of the image even in a recording medium such as plain paper. The ink jet ink set has a first ink and a second ink independently, and is used so that the first and second inks overlap each other at least partly upon application of the inks to a recording medium. The first ink contains at least a pigment and a silicone oil. The second ink contains at least a pigment and a graft polymer that includes at least a nonionic unit represented by the general formula (I) and a unit having a polysiloxane structure.

摘要:
A pigment ink is provided which has good ink reliability and storage stability and can achieve superior scratch resistance of images at such a level that coloring materials are hardly scraped off even when images are scratched with finger nails under application of such strong pressure as to scratch a recording medium at its non-recorded areas. The pigment ink contains a pigment, a modified siloxane compound having a specific structure, and a polymer whose acid value and hydrogen bond parameter (δh) are specified.

摘要:
To enable a bunch of sheets to be reliably discharged to a stack tray, also in the case where weight of the bunch of sheets formed on a processing tray is large, upon receiving a printing command, a main body control section checks information on an ink discharge amount in printing on a sheet, the number of sheets, sheet type and printing mode (two-side/one-side). By this means, the section recognizes weight of the bunch of sheets formed on the processing tray, and when determining that the weight is heavier than predetermined weight, deceases an upper limit value of the number of sheets of a bunch of sheets formed at a time to report to a user.
