Abstract: This invention relates to bonding coats and top coats made of aliphatic, segmented polycarbonate-polyurea elastomers for coating textile substrates. The coats are applied to the substrates from their solutions by the reverse roll coating process. The coating used has the advantage of providing resistance to hydrolysis, light fastness, unlimited pot life and can be prepared with inexpensive and physiologically harmless solvents. The synthetic leather has a high abrasion resistance, high folding strength, high flexibility in the cold and resistance to alcohol.
