摘要:
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.
