Synthetic latex is widely used as a binder in paper coating. The coating is described as a porous mineral structure, whose pores are covered by latex particles. During the Printing process, the penetration of water and ink is controlled by the interfaces within the layer. The adhesion of the latex on the particle of pigment, and then the cohesion of the layer, are also governed by the structure of the latex film. Therefore studying the formation processes of pure latex film is of fundamental interest.
In this work, we have used Small Angle Neutron Scattering and Transmission Electron Microscopy to review the different steps of film formation and the resulting structural changes as function of the nature of the latex and of the drying conditions. We discuss the influence of the final latex film structure on coating layer properties.
