Abstract

Polyurethane moldings having an inhomogeneously colored surface with color contrasts in fiber-like distribution are made by incorporating colored fibers of a specified type in a polyurethane forming reactionmixture. The colored fibers must have a staple length of from 0.1 to 6 mm, a denier of from 0.1 to 25 dtex, and a coloring agent that does not migrate or dissolve in the polyurethane-forming materials. These fibers are generally used in a quantity such that they represent from 0.1 to 10 wt. % of the polyurethane-forming reaction mixture. Shoe soles, shoe heels, multiple layer soles and padded components are examples of moldings which may be produced in accordance with the present invention.
