摘要：
A method and a composition for the production of surface smoothing polyurethane layers for application to a substrate prior to subsequent application of a charge generation layer for electrophotographic applications by preparing a coating solution containing a dialkyl malonate capped isocyanate or polyisocyanate, a polyol and at least one finely-divided metal oxide, coating the substrate with the coating solution and heating the coating solution to a temperature up to about 140° C.
