た多色カラー画像を与えるインクジェット記録方法に関
する。Detailed Description of the Invention (Industrial Application Field) The present invention relates to an inkjet recording method, and more specifically, it provides a multicolor image that has dark and light areas and has excellent light resistance in light and mixed color areas. This invention relates to an inkjet recording method.
（従来の技術）
インクジェット記録方法は、記録ヘッドのノズルからイ
ンクの液滴を吐出させ、このインク滴を紙、布等の被記
録材に吸収させて画像等の記録を行うものであり、騒音

かも高速記録、多色カラー画像記録の可能な記録方法で
ある。(Prior Art) The inkjet recording method records images by ejecting ink droplets from the nozzles of a recording head and absorbing the ink droplets into a recording material such as paper or cloth. This is a recording method that causes less blemishes, does not require special fixing treatment, and allows high-speed recording and multi-color image recording.

々のインクを混合吸収させて多色カラー画像の記録を行
うものである。Multicolor images can be recorded in yellow (Y), magenta (
This is done by subtractively mixing three primary colors of M), cyan (C), or four primary colors including black (Bk). In other words, three colors of ink or four colors of ink including black are ejected from dedicated nozzles for each color of the recording head while controlling the ejection amount of each ink, and each ink is applied to one pixel of the recording material. A multicolor image is recorded by mixing and absorbing the images.
（発明が解決しようとしている問題点）上記多色カラー
画像の形成に際しては色の違いだけではなく、色の濃淡
をも形成し、更に中間色領域の形成も必要である。(Problems to be Solved by the Invention) When forming the above-mentioned multicolor image, it is necessary to form not only color differences but also color shading, and furthermore, it is necessary to form intermediate color areas.
濃淡部の形成は、染料濃度の異なる二種以上のインクを
用いて行われ、又、中間色は異なるインりの混色（被記
録材上での）によって形成される。The formation of the dark and light areas is performed using two or more types of ink having different dye concentrations, and the intermediate color is formed by mixing different ink colors (on the recording material).
このように濃淡及び中間色領域を有する多色カラー画像
は、勿論種々の特性、特に全体的に鮮明性及び耐光性に
優れることが理想であるが、現状では十分な鮮明性及び
耐光性を同時に与える染料は開発されていない。Ideally, a multicolor image with such shading and intermediate color areas should have various properties, especially excellent overall clarity and light fastness, but currently there is no way to simultaneously provide sufficient sharpness and light fastness. No dyes have been developed.
すなわち、−船釣に鮮明性に優れる染料は耐光性に劣る
傾向があり、一方、耐光性に優れる染料は鮮明性に劣る
傾向がある。That is, dyes with excellent brightness for boat fishing tend to have poor light fastness, while dyes with excellent light fastness tend to have poor brightness.
従ってこれらの染料で多色カラー画像を形成すると鮮明
な画像は耐光性が劣り、一方、耐光性に優れる画像は鮮
明性に劣る傾向がある。Therefore, when multicolor images are formed using these dyes, sharp images tend to have poor light fastness, while images with excellent light fastness tend to have poor sharpness.
特に多色カラー画像が濃淡部を有する鮮明な画像の場合
には淡色部の光褪色が速やかで、短時間に著しく画像品
質が低下するという問題がある。In particular, when a multicolor image is a clear image having light and dark areas, there is a problem in that the light color areas are quickly photofaded, resulting in a significant deterioration in image quality in a short period of time.
特にこの場合において、淡色の中間色領域Ｊすなわち、
原色インクの混色部は染料の相互作用によって一層光褪
色が促進される傾向がある。Particularly in this case, the light intermediate color area J, that is,
Color-mixed areas of primary color inks tend to undergo further photofading due to the interaction of dyes.
例えば、耐光性、鮮明性等の面からシアン染料には銅フ
タロシアニン染料を用いるのが一般的である。しかし、
銅フタロシアニン染料が触媒となり、一部のマゼンタ染
料の光劣化を促進し、その混色部におけるマゼンタの褪
色を加速する傾向があることが明らかになった。For example, copper phthalocyanine dyes are generally used as cyan dyes in terms of light resistance, sharpness, and the like. but,
It has been revealed that copper phthalocyanine dye acts as a catalyst and tends to accelerate the photodegradation of some magenta dyes, accelerating the fading of magenta in the color mixture area.
そこで、鮮明性には劣るが、マゼンタの耐光劣化を促進
させないシアン染料を淡インクとして用いる方法が提案
された。しかしこの方法では、淡色マゼンタインクと濃
色シアンインクとの混色部におけるマゼンタの耐光劣化
を抑制することはできなかった。Therefore, a method has been proposed in which a cyan dye is used as a light ink, but does not accelerate the light fastness deterioration of magenta, although it is inferior in clarity. However, with this method, it was not possible to suppress the deterioration of the light resistance of magenta in the color mixture area of the light color magenta ink and the dark color cyan ink.
本発明の目的は、鮮明な画像であり、しかも淡色部や中
間色領域の耐光性にも優れた多色カラー画像を提供する
ことである。An object of the present invention is to provide a multicolor image that is a clear image and also has excellent light resistance in light color areas and intermediate color areas.
（問題点を解決するための手段） 上記目的は以下の本発明によって達成される。(Means for solving problems) The above objects are achieved by the present invention as described below.
すなわち、本発明は、マゼンタインクを含む２色以上の
インクを用い、少なくともマゼンタインクについては染
料濃度の異なる２種以上のインクを用いて記録を行うイ
ンクジェット記録方法であって、マゼンタインクのうち
少なくとも２種のインク間で用いる染料が異なることを
特徴とするインクジェット記録方法である。That is, the present invention is an inkjet recording method in which recording is performed using two or more color inks including magenta ink, and at least two or more types of ink having different dye concentrations for the magenta ink, wherein at least one of the magenta inks is used for recording. This is an inkjet recording method characterized in that two types of ink use different dyes.

も染料濃度の低い淡色インクの２種以上を用いる。濃色
インクは多色カラー画像の高濃度領域を、そして淡色イ
ンクは多色カラー画像の淡色領域又は混色領域を形成す
る。The ink used in the present invention is preferably an ink of the three primary colors of yellow, magenta, and cyan, or four primary colors with black added thereto. Among these inks, at least the magenta ink is a dark color ink with a high dye concentration and Use two or more types of light-colored ink with a lower dye concentration than the above. Dark inks form high density areas of a multicolor image, and light inks form light or mixed areas of a multicolor image.
濃色インクに用いる染料は鮮明性を主眼として選択し、
一方、淡色インクに用いる染料は耐光性及び他の染料へ
の影響を主眼にして選択する。The dyes used for dark ink are selected with clarity as the main focus.
On the other hand, dyes used for light-colored inks are selected with emphasis on light fastness and influence on other dyes.
濃色インク用のマゼンタ染料としては、鮮明性に優れ、
ある程度の耐光性を有する染料が好ましい。このような
染料として、例えば、Ｃ，１，アシッドレッド３５．３
７．４２．１０６．１８６、Ｃ，１，リアクティブレッ
ド１８０等が挙げられる。As a magenta dye for dark ink, it has excellent clarity and
Dyes with some degree of light resistance are preferred. Such dyes include, for example, C,1, Acid Red 35.3.
7.42.106.186, C,1, Reactive Red 180, and the like.

レクトレッド８１、Ｃ，１，リアクティブレッド１２０
等が挙げられる。The first condition for a magenta dye for light-colored inks is that it has light resistance and does not promote photofading even when mixed with inks of other colors. Examples of such dyes include C,L acid red 214, C,1,direct red 81, and C,1,reactive red 120.
etc.
又、濃淡インクは、濃色インクと淡色インクの２種と限
定されず、そｈらの中間濃度のインクを用いてもよいの
は当然である。Further, the dark and light inks are not limited to two types, dark color ink and light color ink, and it is natural that ink having an intermediate density between them may be used.
濃色インクの染料濃度は用いる染料のカラーバリユーに

淡色インクの場合は同様に約０．０１乃至２重量％程度
であり、中間濃度インクはそれらの中間の０．１乃至３

マゼンタ色を表すことができるが、極端にカラーバリユ
ーの低い染料、例えば、ｃ、ｉ、リアクティブレッド１
２０は、同範囲のマゼンタ色を表現するには１．３重１
％の濃度が必要となる。The dye concentration of dark ink depends on the color value of the dye used, but numerically it is about 0.8 to 5%,
Similarly, in the case of light color ink, it is about 0.01 to 2% by weight, and for medium density ink, it is about 0.1 to 3% by weight.
．． It is about 0% by weight. For example, C,1, Reactive Red 180 has a relatively high color value, and an ink with a dye concentration of 0.2% by weight can produce a magenta color with a reflection density of 0.1 to 0.5; dyes with low color value, such as c, i, reactive red 1
20 is 1.3 times 1 to express the same range of magenta color.
