  The invention relates to an image support medium for creation of an aesthetic image that is an work or object for display. This support medium includes a polymer in an amount sufficient to enable the image to have at least one aesthetic element. In different embodiments, the image support medium is an image support stabilizer, the polymer is a synthetic absorbent or conductive polymer, or the polymer is a transparent or synthetic translucent polymer and a property of this transparent or translucent polymer is enhanced to facilitate the creation or preservation of the image by at least one stabilizer. The invention also relates to a method for preparing this image support medium. The method includes forming a reaction mixture comprising a monomer in an amount sufficient to provide or enable the image to have an aesthetic element, and processing the reaction mixture into a 2- or 3-dimensional shape.

  本发明涉及一种图像支持介质，用于创建作为作品或展示对象的美学图像。这种支撑介质包括一种聚合物，其用量足以使图像具有至少一种审美元素。在不同的实施例中，图像支持介质是一种图像支持稳定剂，聚合物是一种合成的吸收性或导电性聚合物，或者聚合物是一种透明或合成的半透明聚合物，并且这种透明或半透明聚合物的特性被至少一种稳定剂增强，以促进图像的创建或保存。本发明还涉及一种制备这种图像支持介质的方法。该方法包括形成由单体组成的反应混合物，其用量足以提供或使图像具有美学元素，并将反应混合物加工成 2 维或 3 维形状。

  AbstractA new monoxanthen‒9‒yl derivative of urea has been synthesized and the structure of this product (N‒9 H‒xanthen‒9‒ylurea) and that of the previously known N,N′‒di‒9 H‒xanthen‒9‒ylurea have been proved by 15N NMR and other spectroscopic techniques. A series of 13C and 15N labeled urea derivatives has been prepared and the utility of their 13C and 15N chemical shifts and coupling constants in the structural analysis of urea derivatives has been investigated.
