Abstract
A method for producing a support for polyurethane-based imitation leather free of dimethylformamide or other solvents or water involves preparing a base. A two-component polyurethane layer is sprayed on the base which includes preparing a first component and a second component. The first and second components are combined to obtain a mixture, and the mixture is sprayed uniformly on the base forming the polyurethane layer. A backing is applied on the two-component polyurethane layer forming a support and the support is dried.
