Abstract: A record sheet for use in an electro-coagulation printing method, which comprises a base sheet and a layer provided thereon composed of at least one filler selected from the group consisting of alumina sol, boemite, pseudo boemite, synthetic amorphous silica, silica sol and colloidal silica and a binder, wherein said record sheet satisfies the following properties; (i) a wet time of the record sheet obtained from a liquid absorption curve of pure water measured by a dynamic scanning absorptometer being not more than 15 milliseconds, (ii) an absorption coefficient of the record sheet obtained from a liquid absorption curve of pure water measured by a dynamic scanning absorptometer being at least 10 ml/m2s−½, and (iii) a contact ratio of the record sheet with the coagulated colloids measured by a specular reflection smoothness tester under a pressure of 40 kg/cm2 with a ray having a wavelength of 0.

Abstract: A liquid electrophotographic development sheet wherein a polyethylene resin or a resin including polyethylene such as a polyethylene ionomer as a main component is present on at least one of the surfaces of a substrate sheet is provided. The development sheet can find wide application such as a newspaper, a magazine, a commercial publication, various publications, a poster, a postcard and an envelope, due to its excellent transfer-fixing property.

Abstract: The present invention provides a record sheet used in an electro-coagulation printing method for forming characters and images on a cylinder as an electrode with an ink which coagulates with electric charge and for transferring the characters and images to the record sheet, wherein the wet time is 15 milliseconds or less, obtained from the absorption curve of pure water measured by a dynamic scanning absorptometer. Preferably, the record sheet has 5 ml/m.sup.2 s.sup.-1/2 or more absorption coefficient, and more preferably, has contact ratio measured by a specular reflection smoothness tester under a pressure of 40 kg/cm.sup.2 with a ray having a wavelength of 0.5 .mu.m is 40% or more. The record sheet can be used for various print sheets, in particular, for business form sheets and newspaper sheets.
