20100033522 | INK SET, INK JET RECORDING METHOD AND INK JET RECORDING APPARATUS - 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/m | 02-11-2010 |
20100033523 | INK SET, INK JET RECORDING METHOD, AND INK JET RECORDING APPARATUS - 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. | 02-11-2010 |
