Abstract: A method is taught for that allows for controlling and optimizing the level of adhesion between a multilayer composite applied to a support web. The method comprises the steps of selecting the support web with or without a subbing layer applied thereto; selecting an organic solvent that is substantially free of other constituents as a carrier layer; forming a multilayer composite including the carrier layer, the carrier layer being the lowermost layer thereof; applying the multilayer composite to the support web or the subbing layer; drying the multilayer composite on the support web, the carrier layer evaporating from the multilayer composite; testing the adhesive strength between the support web or subbing layer and the multilayer composite after drying; and repeating these steps until a desired level of adhesion is found.

Abstract: Thermographic and photothermographic materials comprise a barrier layer to provide physical protection and to prevent migration of diffusible imaging components and by-products resulting from high temperature imaging and/or development. The barrier layer comprises a film-forming acrylic or methacrylic acid ester or amide polymer(s) that has a molecular weight of at least 8000 g/mole and comprises hydroxy functionality in from about 15 to 100 mole % of the acrylic or methacrylic acid ester or amide recurring units. This barrier layer is capable of retarding diffusion of mobile chemicals such as fatty carboxylic acids, developers, and toners. This barrier layer can also include at least one other film-forming polymer to provide a clear and scratch-resistant surface.

Abstract: A viscosity-increasing agent, capable of increasing the viscosity of a film-forming polymer in an image-functional layer, is preapplied in a first solution onto a web through a coating and drying process. When a second solution containing the film-forming polymer is then coated on the web, the viscosity-increasing agent diffuses through the applied second solution. As the viscosity-increasing agent interacts with the film-forming polymer during this diffusion process, the viscosity of the solution increases. The invention can be used to improve the manufacture of ink-jet media, photographic or photothermographic elements, and other imaging and image-receiving media.
