Waterproof receiver sheet for toner images |
摘要 |
A toner image receiver sheet for electrophotography comprises a substantially opaque substrate of microporous material and, disposed on at least one surface of the substrate, a substantially water-impervious toner image-receiving layer comprising a thermoplastic organic polymer. The microporous material of the substrate comprises a matrix of substantially water-insoluble organic polymer in which is distributed finely divided substantially water-insoluble filler particles that are at least 50 weight percent siliceous particles and constitute about 40 to 90 weight percent of the microporous material. A network of interconnecting pores communicating throughout the microporous material constitutes about 35 to 95 volume percent of the microporous material. On at least one surface of the substrate is disposed a substantially water-impervious toner image-receiving layer comprising a thermoplastic organic polymer. The toner image receiver sheet is substantially impervious to water and has a volume resistivity of about 1x108 ohm-cm to 1x1013 ohm-cm, preferably about 1x1010 ohm-cm to 1x1012 ohm-cm. In a process for forming the just-described toner image receiver sheet, the toner image-receiving layer is preferably applied on at least one surface of the substrate using a water-dispersible composition of a thermoplastic organic polymer.
