Abstract
A plurality of polyurethane layers, some of which have a contrasting color with respect to an adjacent layer is formed into a laminate. During preparation, each layer is separately formed, as by spraying, and the contrasting color ensures that the preceding layer can be fully covered. The laminate can be utilized to cover areas or objects which are otherwise difficult to ensure that it has a continuous or complete coating. The invention is suitable for use as a coating and for the preparation of various in situ articles or enclosures, for example a fuel tank, such as commercial and military aircraft.
