<P>PROBLEM TO BE SOLVED: To provide a composition for a nonslip material having a high sliding resistance and durability against running of vehicles over a long time, which are required by a parking lot or the like. Ž<P>SOLUTION: The composition for a polyurethane urea nonslip material comprises a base compound, a curing agent and an inorganic aggregate. A compound prepared by adding a diol containing a bisphenol group to attain a bisphenol group content falling within a limited range is used as a polyol constituent constituting the base compound. As a primary constituent of an isocyanate reaction constituent of the curing agent, 4,4'-methylene-bis-(2-chloroaniline) is used. The primary agent and the curing agent are mixed in such a ratio that the equivalent ratio of the isocyanate group of the base compound to the isocyanate reaction constituent of the curing agent falls within a specified range. A certain range of the inorganic aggregate is added to the mixture, and the resulting mixture is cured to obtain the composition for a polyurethane urea nonslip material.
