    • In a dye image forming process in color photography comprising imagewise exposing a photographic element comprising a support and a light sensitive silver halide emulsion layer, and processing the exposed photographic element with an alkaline processing solution in the presence of a dye developer whereby a dye image corresponding to the imagewise exposure is formed by oxidation of said developer as a function of development of silver halide, the improvement which comprises the dye developer being a mono azo dye developer represented by the following formula:X--N.dbd.N--Y--NH--Zwherein X represents a monovalent group selected from an aromatic group, a non-aromatic-heterocyclic active-methylene-containing group, a non-aromatic-heterocyclic active-methyne-containing group, an aliphatic active-methylene-containing group, and an aliphatic active-methyne-containing group; and Y and Z respectively represent divalent and monovalent groups of an aromatic group, at least one of the X, Y and Z has therein at least one of the developer groups which are either capable of developing silver halide or changeable to a group capable of developing silver halide, the azo radical (--N=N--) and the secondary amino radical (--NH--) are respectively attached to the adjacent carbon atoms in Y, the azo radical being attached to an aromatic ring of the aromatic group of X or to the active methylene or methyne of X and is attached to an aromatic ring of the aromatic group of Y, and the amino radical is attached to aromatic rings of Y and Z.
    • 在彩色摄影中的染料成像过程中,包括将包含载体和感光卤化银乳剂层的照相元件成像曝光,并在染料显影剂存在下用碱性处理溶液处理曝光的照相元件,由此染料图像对应 通过作为卤化银显影的函数的所述显影剂的氧化形成图像曝光,其改进包括染料显影剂是由下式表示的单偶氮染料显影剂:XN = NY-NH-Z其中X表示 选自芳族基团,非芳香族 - 杂环类活性亚甲基基团,非芳香族 - 含杂环式含活性甲基的基团,含脂肪族活性亚甲基基团和脂肪族活性甲基 - 含有组; Y和Z分别表示芳族基团的二价和一价基团,X,Y和Z中的至少一个在其中具有能够显影卤化银或能够显影的基团中的至少一种显影剂组 卤化银,偶氮基(-N = N-)和仲氨基(-NH-)分别连接到Y中的相邻碳原子上,偶氮基连接到X的芳族基团的芳环上或 与X的活性亚甲基或次炔连接并连接到Y的芳族基团的芳环上,并且氨基连接到Y和Z的芳环上。
