摘要： This invention relates to electrophotographic elements containing a layer formed from coating compositions containing a mixture of polymeric binders, including a polyvinyl butyral and a polyester ionomer and a crystalline mixture of unsubstituted titanyl phthalocyanine pigment, titanyl phthalocyanine pigments or mixtures thereof dispersed in the mixture. More particularly the invention relates to electrophotographic elements containing photoconductive layers which are especially useful for forming a photoconductive layer that is very uniform and highly absorptive at relatively thin coverage with good inter layer adhesion. The electrophotographic elements produced using this coating composition are particularly suited for high quality applications such as providing copy images with very low grain.

摘要： A method for controlling the thickness and uniformity of a dip coated layer, using a coating apparatus in a normal coating environment, includes the following steps: forming under normal coating conditions of ambient temperature and relative humidity a series of coated layers on a metal substrate having a thickness of at least about 500 microns, using variations in coating solution viscosity m, coating substrate withdrawal speed v, capillary number Ca, coating solution surface tension S, and boiling point bp (a correlative of evaporation rate)of the coating solution solvent, a coated layer including at least a portion of uniform thickness T(even) and, optionally, a portion of non-uniform thickness L (uneven); statistically analyzing measurements carried out on the series of coated layers and generating the constants, a, b, c, d, and e for Equations 2, 3, and 4: T(even)=a+b(m*v) (Equation 2) L(uneven)=c+d*(v*bp)+e*(Ca*bp) (Equation 3) v(even)=−c/bp*(d+e*m/S) (Equation 4) using Equation 4, determining the coating speed v(even) producing the maximum thickness of a coated layer having a completely uniform thickness for a given set of coating solution characteristics; and using Equation 2, determining the thickness T(even) of the portion of the coated layer having uniform thickness for a given set of coating solution characteristics and the coating speed determined in step (c).

摘要： Disclosed are photoconductive elements including a conductive support, e.g., an electrically conductive film, drum, or belt, on which a negatively chargeable photoconductive layer is disposed. An electrical barrier layer is disposed between the conductive support and the photoconductive layer. The barrier layer provides a high energy barrier to the injection of positive charges, but transports electrons under an applied electric field. In embodiments, the barrier layer can transport charge by electronic, or both electronic and ionic mechanisms, and, is not substantially affected by humidity changes. The barrier layer includes a polyester-co-imides, polyesterionomer-co-imides, or polyamide-co-imides having covalently bonded as repeat units in the polymer chain, aromatic tetracarbonylbisimide groups of the formula: wherein Ar1 and Ar2 respectively represent tetravalent or trivalent aromatic groups of 6 to about 20 carbon atoms, and X is O, C(CF3)2, S═O or SO2.
