Abstract

A stiff, water resistant laminated medical or veterinary dressing is described along with a procedure for forming the final hardened dressing. The dressing is obtained by treating a gypsum bandage with an aqueous dispersion of a synthetic resin and then forming a layer from it which is immediately adjacent to a layer formed from a water hardenable synthetic resin bandage. Either layer may be formed first and further layers may be formed so long as the layers alternate between those formed from wraps of the gypsum bandages and those formed from wraps of the synthetic resin bandage.
