Abstract

The process for the preparation of containers comprising two or more partial regions separated from each other of solid cast powder formulations having different colors employs containers into which separating bridges of a pasty composition have been injected, said composition being similar to the subsequently cast solid powder formulations. The bridges prevent the partial regions having different colors from coalescing.
