摘要： A color negative photographic element is disclosed containing yellow, magenta and cyan dye-forming couplers and masking dyes. Visual judging of the negative image obtained following processing is facilitated by choosing the masking dyes to provide, following imagewise exposure and processing, in CIE1976(L.sup.* a.sup.* b.sup.*) color space L.sup.* values of greater than 30 and C.sup.* values of less than 20, where C.sup.* values are derived from the formula: C.sup.* =[(a.sup.*).sup.2 +(b.sup.*).sup.2 ].sup.1/2.

摘要： A coating composition for use in forming an overcoat layer in a photographic element, said composition comprising an aqueous solution of: a mixture of two or more surfactants; a hydrophilic binder; matte beads; and a lubricating agent; wherein one of the surfactants is represented by the following Formula (I) and is the only fluorosurfactant in the composition: Rf—CH2CH2—S-(A)-D (I) where Rf is —(CF2)nCF3, n represents the number of CF2 groups and is 3 or 5 in at least 60% of the Rf groups present, and in the remainder of Rf groups n is 7, 9, or 11. A is a divalent linking group that includes substituted alkylene or alkylene (N-alkylene)amide; and D is an ionic group. A photographic element with an outermost layer containing the coating composition is also disclosed.
摘要翻译：一种用于在照相元件中形成外涂层的涂料组合物，所述组合物包含水溶液：两种或更多种表面活性剂的混合物; 亲水性粘合剂; 哑光珠; 和润滑剂; 其中一种表面活性剂由下式（I）表示，并且是组合物中唯一的含氟表面活性剂：其中R f是 - （CF 2）n CF 3，n表示CF 2基团的数目，并且在至少60％的 Rf基团存在，Rf基团的其余部分为7,9或11.A为包含取代的亚烷基或亚烷基（N-亚烷基）酰胺的二价连接基团; 并且D是离子基团。还公开了具有包含该涂料组合物的最外层的照相元件。
