As PU leather materials in mostly brownish, reddish or black colors and a glossy surface and an antique look were wrongly designated. Among other things, it was sold as "Bycast Leather", "Leather Milling", PU leather or (incorrectly) as leather with a "pull-up look" or "pull-up leather" (Pull-up leather in the strict sense of the word means a type of fat leather) It is dyed cow split leather with an embossed and colored surface. The surface coating was usually made of 100% polyurethane. The surface of the artificial leather is also 100% polyurethane.

Sending the word "leather" in the name is not permitted in either case. Foil-coated split leather and artificial leather may not be declared as "leather".

The advantage of these materials is the price. Split leathers are inexpensive, but i. d. Usually not particularly durable. The polyurethane coating gives the leather the necessary stability. The disadvantage is the lack of breathability. Due to the strong coating, the leathers are “colder” than uncoated leathers and tend to stick to the skin.

Due to the strong coating, the need for care is completely different from that of uncoated leathers. With these leathers, the focus is not on “leather care”, but rather the care of the polyurethane coating, as care products cannot penetrate the upper coating. If necessary, these leathers and artificial leathers should be dusted with a lint-free dry or only slightly damp cloth. The leather should be cleaned and cared for every 3 to 6 months.
