[0120] Preparation of Electrophotographic Toner-Receiving Layer (TRL)

[0121] A 32 weight percent aqueous solution of a mixture of AQ 55 and Kaogloss 90 in the weight ratios specified in Table 1 was coated on corona discharge treated, polyethylene resin coated paper as described above to obtain 10.76 g / m of AQ55 2 Dry coverage of the coating. A control coating that did not include clay was also prepared. The TRL coated and control papers were printed on a KODAK NEXPRESS 2100 printing press. Writability was evaluated by writing on the surface of the printed sheet with a No. 2 pencil and / or ballpoint pen. Wherein the desired printed sheet was belt fused at 165°C, 6 ips, 35 psi (nip pressure) using a 3 mil polyimide belt in an off-line belt fuser. Gloss measurement results (60) were obtained on tape fused samples using a BYK Gardner Glossmeter in Dmin (white) and Dmax (black area).

Abstract

The present invention relates to a method of forming an electrophotographic print comprising providing an image receiving element having a writable toner receiving layer on each side, wherein each said toner receiving layer comprises a thermoplastic polymer and an oil sorbent an additive, said additive being present in an amount of 10% of said toner receiving layer, forming a toner image on at least one side of said image receiving member, fusing said at least one toner image, making said image The receiving element is passed through a ribbon fuser with the image bearing surface of the image receiving element abutting against the ribbon fuser to provide a ribbon fused element having the property: between the receiving element and the ribbon The adjacent side of the fuser has a glossy finish while the other side remains a writable surface.

Description

field of invention [0001] This invention relates to paper for electrophotographic printing. In a preferred form, it involves an image receiving element that is writeable on both sides, forming a near photographic quality electrophotographic print that includes an image bearing side with a glossy surface, while the other side remains writable surface. Background technique [0002] It is highly desirable to use electrophotographic imaging techniques to produce near photographic quality images. There is a greater need to produce such images on substrates that give prints the look and feel typical of photographic prints produced with silver halide imaging techniques, such as degree and uniformity of gloss, stiffness, and opacity, and high resolution of a correspondingly low-grain appearance rate and sharpness. Advantages of using digital electrophotography to produce photographic-quality images on such substrates include improved environmental friendliness, ease of use, and v...
