    • Silver halide color photographic materials, and processes for processing photographic materials, are described, involving the use of at least one of a compound represented by formula (I) and a compound represented by formula (II) ##STR1## wherein A represents an n-valent aliphatic linkage group, an aromatic linkage group or a heterocyclic group (when n is 1, A represents an aliphatic group, aromatic group, heterocyclic group, or hydrogen atom); X represents --O--, --S--, or ##STR2## (wherein, R.sup.4 represents a lower alkyl group); R.sup.1 and R.sup.2 each represents a substituted or unsubstituted lower alkyl group; R.sup.3 represents a lower alkylene group; said R.sup.1 and R.sup.2, said R.sup.1 and A, said R.sup.1 and R.sup.3, said R.sup.2 and A, or said R.sup.2 and R.sup.3 combine with each other to form a ring; Y represents an anion; l represents 0 or 1; m represents 0 or 1; n represents 1, 2, or 3; p represents 0 or 1; q represents 0, 1, 2, or 3; when n is 2 or 3, the substituents bonding to A are the same or different; r represents 1, 2, or 3; R.sup.11 and R.sup.12 each represents a hydrogen atom, an alkyl group, or an acyl group, except that R.sup.11 and R.sup.12 do not both represent hydrogen atom at the same time; or R.sup.11 and R.sup.12 combine with each other to form a ring.
    • 描述了卤化银彩色照相材料和用于加工照相材料的方法,涉及使用由式(I)表示的化合物和由式(II)表示的化合物中的至少一种。 (II)其中A表示n价的脂肪族连接基,芳香族连接基或杂环基(n为1时,A表示脂肪族基,芳香族基,杂环基或氢原子)。 X表示-O - , - S-或(其中,R4表示低级烷基)。 R 1和R 2各自表示取代或未取代的低级烷基; R3表示低级亚烷基; 所述R1和R2表示R1和A表示R1和R3表示R2和A,或所述R2和R3相互结合形成环; Y表示阴离子; l表示0或1; m表示0或1; n表示1,2或3; p表示0或1; q表示0,1,2或3; 当n为2或3时,与A键合的取代基相同或不同; r表示1,2或3; R 11和R 12各自表示氢原子,烷基或酰基,不同之处在于R 11和R 12不同时同时表示氢原子; 或R11和R12彼此结合形成环。
