Abstract

A method of improving adhesion to aluminum surfaces prior to fusing by using plasticizers in members having photoconductive particles dispersed in an insulating resin matrix. The photo-conductive particles are present in an amount from about 1 to 25 percent by volume of the layer. The photoconductive par-ticles are dispersed in a controlled manner so as to form a plurality of continuous paths through the thickness of the layer. More specifically, plasticizers such as Santicizers® made by Monsanto, i.e., toluene sulfoarnide, cresyl phosphates and phthalates, are disclosed. In the fabrication, the layers are made with slurries of dispersed and suspended pigment particles as well as polyester matrix particles. The fabrica-tion formulation ideally uses vehicles which do not attack either the pigment or the polyester matrix particles in order to preserve and maintain the controlled geometry However-, the dried layer exhibits very poor adhesion on aluminum sur-faces prior to fusing. This problem hinders the system's scale-up potential. Therefore, the incorporation of small amounts of plasticizers, i.e., Santicizers ® available from Monsanto Chemical Company, greatly improves the adhesion of these dried layers to the aluminum substrates prior to fusing. Using this process, it is now possible to use a conventional commercial coating machine without any adhesion problems. In addition, due to the plasticizing properties, the resultant fused layer exhib:Lts improved flexibility.
