Résumé :	Dyeing is a significant process step in leather making that is carried out to enhance the aesthetics of the tanned hides and skins. Due to the heterogeneous nature of the skin matrix, obtaining leathers with consistent color is challenging. The present study describes application of hydrotalcite-like inorganic synthetic material (HTLM) during leather dyeing to bring color uniformity among leathers by maximizing the color intensity within the skin and among the skins processed in a batch. The HTLM has been used in an interim step between two phases of dyeing that enhanced shade intensity as well as color consistency through modification of the leather surface chemically. The efficacy of the HTLM for enhanced color intensity and uniformity in leather has been investigated. Influence of the HTLM on the physicals characteristics like, perspiration, color fastness to light and dry/wet rub are also studied.
