semianiline

Semianiline is a category in leather finishing used to describe hides that have been dyed with a transparent or semi-transparent dye and then finished with a protective layer that may include a small amount of pigment.

In manufacturing, the process typically begins with aniline or semi-aniline dyeing of the leather to impart color, followed by a light seal or topcoat, often polyurethane or acrylic, to improve stain resistance and durability. The pigment is used sparingly to preserve grain.

Characteristics: preserves natural grain and softness, yields more even color than pure aniline, offers better stain and abrasion resistance than aniline; color depth tends to be less intense and slightly more uniform.

Applications and market: common for high-end furniture, automotive interiors, footwear and designer handbags. Maintenance considerations include avoiding harsh solvents and prolonged exposure to direct sunlight to prevent fading.
