The invention provides electrographic imaging sheets comprising a substrate carrying a layer of dielectric material which has abhesive properties suitable for the release of a multicolored toner image from the dielectric surface during image transfer, while also having good toning properties during the several development stages of a multicolor toner imaging process.

A sash is constructed of two fabric segments. A first fabric segment comprises reflective fabric to offer increased visibility to the wearer at night. The first fabric is mitered to an angle of between 75 and 115 degrees at midpoint where it rests on the hip of the wearer. A second fabric segment is attached to ends of the reflective fabric to form a support segment which would lie on the shoulder of the wearer. The support segment is attached to the first section at an angle of between 110 and 165 degrees so that the support segment will lie flat on the shoulder of the wearer. The combination of the mitered angle at the midpoint of the first fabric and the angle at the point of attachment of the reflective fabric and the support segment provide a design which lies flat on the torso of the wearer so that the reflective fabric is oriented properly for optimal viewing.

An electrographic imaging process is described in which electrostatic images are toned in sequence to form a multicolor intermediate image on a temporary dielectric receptor. The intermediate image is then transferred to a permanent receptor. Certain relative properties of the toner and the intermediate image, such as surface energy, T.sub.g, work of adhesion, and complex dynamic viscosity, have been found to be important to the production of good final images.

Composite, liquid-sorbent media which can be applied to various substrates to provide improved liquid-sorbent materials. The composite media comprise a liquid-sorbent underlayer and, overlying said underlayer, a liquid-permeable surface layer, the liquid sorptivity of said underlayer being greater than the liquid sorptivity of said surface layer. Transparent sheets having the liquid-sorbent composite media coated on the surface are described as a preferred embodiment of the invention.

Liquid sorbent materials

Transparent sheet material comprising a transparent backing having an ink-receptive stratum thereon. The ink-receptive stratum comprises either a mixture of two polymers or individual layers of each polymer. One polymer is the reaction product of an epoxidized, water-insoluble, neutral rubbery polymer and a water-soluble secondary mono amine and the second polymer contains the repeating units ##STR1##
