    For interfacial interactions of “separable type” the existence is proved of stable multiphase equilibrium states minimizing the total energy. The total energy includes a deformation dependent contribution along sharp interfaces separating the phases. The second gradients of deformation do not occur; the theory is based on interfacial null lagrangians as determined in earlier works of the author. The interfacial interaction is always of separable type if the number of phases does not exceed 3Û for the remaining cases, the separable nature of the interface interaction is an assumption.
