Abstract: An electrophotographic element comprises: an electrically conducting layer, a charge generating layer overlying the electrically conducting layer, and a charge transport layer overlying the electrically conducting layer. The charge transport layer, which can be an overcoat overlying the charge generating layer, comprises the reaction product in an aqueous medium of a mixture comprising a silsesquioxane polymer and a hole transport compound that comprises a tertiary arylamine containing at least one alcoholic or one phenolic hydroxy substituent.

Abstract: Phthalocyanine compositions and prepartion methods. In a method, first, a phthalocyanine mixture is synthesized that has a plurality of differently substituted phthalocyanines selected from the group consisting of compounds having the general structure: ##STR1## M represents a pair of hydrogen atoms or a covalent or coordinate bonded moiety including a metal atom. Each T substituent is independently selected from the group consisting of H, F, Cl, Br, I, and alkyl having from 1 to 18 carbons. There are at least two different T substituents. The smallest T substituent has a van der Waal's radius that differs from the radius of the largest T substituent by less than about 50 percent of the radius of the smallest substituent. The amorphousness of the phthalocyanine mixture is then imcreased. The amorphous mixture is then contacted with organic solvent having a gamma.sub.c hydrogen bonding parameter of less than 8.0.

Abstract: An image-recording element for an ink-jet printer comprising, in the following order:(a) a substrate;(b) a solvent-absorbing gelatin layer and(c) a single image-forming layer of porous, pseudo-boehmite having an average pore radius of 10 to 80 .ANG..
