Compare to this matching Leather Doctor description of Aniline (A.f) – Full:
Aniline leather is soft and natural. They are usually first treated with transparent dyestuff to make the grain and natural characteristics more visible. Modern tannery dyeing is done in a rotating drum in a continuous process follows with fatliquoring. When dried thereafter, the leather goes through another selection or grading to decide the best treatment to bring out their potential softness and natural look. Thus, further sub-divide into various varieties. However, the bulk of aniline leathers after dyeing may reveal uneven grain dye absorbency and too many faults, so that the variation in color over the entire grain surface is too great for many leather fabrications. Varieties of aniline leathers may be referred to as “full sauvage aniline” with an even appearance but not to be mistaken for a lower grade semi-aniline which has micro-pigment coating.
