摘要:
Disclosed is a liquid composition that, while maintaining good color developing properties and gloss, can realize good cleaning operation without staying of the liquid composition in a cleaning cap. The liquid composition is adapted for use with an ink composition for deposition on a recording medium and comprises a modified polyallylamine, a water soluble organic solvent, and water and is free from any colorant. The liquid composition and an ink composition each are deposited onto a recording medium to perform recording. A polymer comprising a recurring unit represented by formula (I) is used as the modified polyallylamine.

摘要:
There is provided an ink composition which can yield records possessing excellent rubbing/abrasion resistance and scratch resistance. Specifically, records possessing excellent rubbing/abrasion resistance and scratch resistance can be produced by using an ink composition comprising: an alkali-soluble copolymer; water; a colorant; and at least one member selected from the group consisting of wax, a viscosity modifier, and a wetting agent. The alkali-soluble copolymer is a copolymer, with an acid value of not more than 40, which is produced by polymerizing an ethylenically unsaturated carboxylic acid monomer and other monomer copolymerizable with the ethylenically unsaturated carboxylic acid monomer in the presence of an alcoholic hydroxyl-containing water-soluble polymer compound or a copolymerizable surfactant and has been adjusted to a pH value, at which the copolymer is soluble in water, by the addition of an inorganic base.

It is an object of the present invention to provide an ink set which has a superior effect in suppressing gloss unevenness of printed images, and which thus makes it possible to obtain images that have a uniform gloss. The present invention achieves this object by providing an ink set comprising one or more color ink compositions containing a pigment as a coloring agent and a dispersing resin that is used to disperse this pigment, and one or more clear ink compositions which contain an aqueous polymer but which contain no coloring agent, wherein the dispersing resin and the aqueous polymer belong to a common category so that the 60° specular gloss (according to JIS Z 8741) of the printed images that are formed by the abovementioned color ink compositions and/or the abovementioned clear ink composition is substantially uniform.

摘要:
The present invention provides an ink set comprising at least three color inks, which are yellow ink whose hue angle H°, as defined in the CIELAB color space on a recording medium (PM photographic paper; same below), is in a range of about 80° to about 110°, magenta ink whose hue angle H° is in a range of about 330° to about 360°, and cyan ink whose hue angle H° is in a range of about 230° to about 260°, and further comprising ink (A) and/or ink (B) described below. With the present ink set, it is possible to provide a highly reliable ink set that can be used in inkjet recording and can produce printed matter having a wide color reproduction range, high color saturation, good graininess, and an adequate glossy look.
摘要:
It is an object of the present invention to provide an ink jet recording method and ink set with which recorded material with excellent gloss and greatly reduced gloss unevenness can be easily obtained without higher costs being entailed, the ink jet recording apparatus having to be modified or made larger, etc., and to provide an ink jet recording method with which a high-quality image can be obtained with a low gloss ratio (maximum value/minimum value) dependent on duty, as well as recorded material produced by this method. The present invention provides an ink jet recording method, in which a pigment ink composition and a clear ink composition containing a resin component are discharged to record information on a recording medium, wherein the discharge amount of the pigment ink composition and/or the discharge amount of the clear ink composition is adjusted so that the gloss will be substantially uniform over the entire recording surface of the recording medium after recording.
摘要:
Ink jet recording is carried out using an ink set including a clear ink composition that contains polymer fine particles and does not contain a colorant, a yellow ink composition, a magenta ink composition, a cyan ink composition, a red ink composition, a violet ink composition, and a black ink composition, whereby a high-quality recorded article having excellent recorded image coloration and glossiness can be obtained.
摘要:
An ink set, exhibiting good ink permeability and fixation, capable of yielding high quality images with no roughness, or an ink set capable of yielding text and/or images of outstanding light resistance, is provided. The ink set of the present invention comprises a dark ink composition and a light ink composition that, while being mutually the same color, are of different color density, and is characterized in that the dark ink composition and the light ink composition each comprise a pigment as a colorant and a resin as a dispersant, in that the ratio between the resin weight proportion B1 and the pigment weight proportion P1 in the dark ink composition (i.e. B1/P1) is lower than the ratio between the resin weight proportion B2 and the pigment weight proportion P2 in the light ink composition (i.e. B2/P2), and in that B1 and B2 differ from each other.
