Abstract
The leather has a finish on a buffed surface. The finish layer is formed in a plurality of layers including an outer layer with a given hardness and a particular surface effect preformed in a hot substrate having a structure corresponding to the particular surface effect the outer layer being formed of a solidified, cross-linked, hydrolysis-resistant, lightfast, polyurethane-containing dispersion, and having a thickness of between 0.01 and 0.08 mm, and an inner layer bonded to the buffed surface leather and comprising a solidified, highly crosslinked, hydrolysis-resistant, lightfast, polyurethane-containing dispersion and having a hardness less than a hardness of the outer layer.

A leather assembly, comprising:
- a leather having a buffed surface;
- a finish layer on said buffed surface, said finish layer comprising a plurality of layers including
- an outer layer with a given hardness and a particular surface structure preformed in a hot substrate having a structure corresponding to the particular surface structure, said outer layer being formed of a solidified, cross-linked, hydrolysis-resistant, lightfast, polyurethane-containing dispersion, and having a thickness of between 0.01 and 0.08 mm, and
- an inner layer bonded to said buffed surface leather and comprising a solidified, crosslinked, hydrolysis-resistant, lightfast, polyurethane-containing dispersion and having a hardness less than a hardness of said outer layer, said inner layer being thinner than said outer layer and comprising two sublayers formed of a solidified, crosslinked polyurethane dispersion and fused to one another by application of pressure and heat.
