PROBLEM TO BE SOLVED: To provide a stainless steel sheet for color development capable of forming a color developing film having color tone uniform in every coil produced, by way of controlling the composition of a passivation film formed on a stainless steel surface and the surface quality in a process of producing a HL product, and a method of producing the same.;SOLUTION: The stainless steel sheet for color development is characterized by having an arithmetic average roughness Ra of the surface of a raw material steel sheet in the vertical direction relative to the sheet passing direction of 0.30 to 1.00 μm, Rsk representing the skewness of the irregularity of the surface thereof of 0.7 to 1.0, and a CrF/FeF ratio namely the ratio of CrF representing the cation fraction of Cr present in the passivation film relative to FeF representing the cation fraction of Fe present in the passivation film of from 16.0 to 20.0.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
