The present invention is directed towards a method of forming a base for an imaging element, which includes providing a support, coating a composition which contains active-hydrogen containing polymers and tris(alkoxycarbonylamino)triazine on a side of the support, and drying the coating composition to form a layer. The present invention is also directed towards a method of forming an imaging element which comprises such a base, which includes the additional step of coating and drying an imaging layer on a side of the support. The invention is further directed towards bases and imaging elements comprising a layer on a side of a support comprising active-hydrogen containing polymers cross-linked with a tris(alkoxycarbonylamino)triazine. In accordance with the invention, a tris(alkoxycarbonylamino)triazine crosslinking agent is employed, which unlike traditional melamine resins, does not emit formaldehyde as a by-product of the crosslinking reaction. This freedom from formaldehyde formation provides an improvement in the manufacturing process because it eliminates the health concerns regarding exposure to formaldehyde and, when the imaging element is a photographic element, permits the preparation of crosslinked coatings that do not adversely effect the sensitometric response of the photographic product.
