A composite laminar structure for producing complementary images in a frangible image-forming substance, and having a strengthened tab portion for facilitation of the separation of the respective sheets of the laminar structure without detachment of the tab portion is described. Thermal imaging composite structures and a method for preparing structures suited to the production of high resolution images in frangible image-forming substance, and especially adapted to sheet separation by mechanical apparatus, are described. <IMAGE> |
