    • A color diffusion transfer photographic element comprising a support having provided thereon a layer containing a dye-providing material associated with a light-sensitive silver halide emulsion, wherein said dye-providing material is a metal chelate compound represented by the following general formula (I) or (II): ##STR1## wherein M.sup.I represents a monovalent, divalent, or trivalent cation; X represents a monovalent, divalent, or trivalent anion; Z and Z.sup.2 each represents an aromatic carbon ring nucleus or heterocyclic ring nucleus having 5 to 7 carbon atoms; G represents a chelating group; Z.sup.1 represents an aromatic carbon ring nucleus or heterocyclic nucleus composed of 5 to 7 atoms; said nucleus having (a) a nitrogen atom, or (b) a carbon atom bonded to a chelating group at the position adjacent to the position bonded to the azo group; Z.sup.3 represents an electron attractive group; Z.sup.4 represents an alkyl group, an aryl group, or a substituted amino group; L represents a ligand including a dye ligand; M.sup.II represents a metal ion weakly coordinated to the dye ligand moiety as compared with the metal ion contained in the image-receiving layer; and p, r and n each is an integer of 0 to 5 and q is 1, 2 or 3 and take a combination that the charges of the total chelate dyes become zero, wherein the chelate compound further contains (1) a carrier component losing the diffusible property or (2) a ballasted carrier capable of releasing a diffusible dye when the silver halide emulsion is developed under an alkaline condition.
    • 一种彩色扩散转印照相材料,其特征在于,具有在其上设置有含有与感光卤化银乳剂相关的染料提供材料的层的载体,其中所述提供染料的材料是由以下通式(I)表示的金属螯合物, 或(II):其中MI表示一价,二价或三价阳离子;(II)其中MI表示一价,二价或三价阳离子; X表示一价,二价或三价阴离子; Z和Z 2各自表示具有5至7个碳原子的芳族碳环核或杂环核; G表示螯合基团; Z1表示由5至7个原子组成的芳族碳环核或杂环核; 所述核具有(a)氮原子,或(b)在与偶氮基键合的位置相邻的位置处键合到螯合基团上的碳原子; Z 3表示吸电子基团; Z4表示烷基,芳基或取代的氨基; L表示包括染料配体的配体; 与图像接收层中包含的金属离子相比,MII表示与染料配体部分弱配位的金属离子; 并且p,r和n各自为0〜5的整数,q为1,2或3,并且组合使总螯合染料的电荷为零,其中螯合化合物还含有(1)载体成分损失 扩散性或(2)当在碱性条件下显影卤化银乳剂时能够释放可扩散染料的压载载体。

    • A cleaning mechanism has a slider moving together with a carriage and a suction cap provided on the slider to cap one of print heads mounted on the carriage to perform suction therefrom. A first contact portion and a second contact portion are provided in each of the carriage and the slider, and a third contact portion and a fourth contact portion are provided in the slider. In the case that the suction cap performs suction from a black head, when the carriage moves toward the cleaning mechanism side, the first contact portion and the third contact portion come into contact with each other to position the carriage and the slider in such a manner that the suction cap faces the black head. On the other hand, in the case that the suction cap performs suction from a color head, when the carriage moves toward the cleaning mechanism side, the second contact portion and the fourth contact portion come into contact with each other to position the carriage and the slider in such a manner that the suction cap faces the color head.
    • 清洁机构具有与滑架一起移动的滑块和设置在滑块上的吸嘴,以盖住安装在滑架上的一个打印头以从中进行抽吸。 第一接触部分和第二接触部分设置在每个托架和滑块中,并且第三接触部分和第四接触部分设置在滑块中。 在吸嘴从黑色头部进行抽吸的情况下,当滑架朝向清洁机构侧移动时,第一接触部和第三接触部相互接触,以使滑架和滑块以这种方式 吸嘴面向黑色头。 另一方面,在吸嘴从彩色头进行抽吸的情况下,当滑架朝向清洁机构侧移动时,第二接触部和第四接触部相互接触以将滑架定位, 滑块以使吸嘴面向彩色头的方式。
