摘要： PURPOSE:To provide the dry silver salt type photosensitive body capable of obtaining high optical density in imagewise exposed parts and stably forming an image small in fog and good in contrast in unexposed parts. CONSTITUTION:This dry silver salt type photosensitive body is composed of a support and heat-developable photosensitive elements comprising (a) an organic silver salt, (b) a reducing agent, (c) a photosensitive silver halide salt or its precursor, and (d) a binder formed in a single layer or multilayers. These heat- developable photosensitive elements contain as the reducing agent the pyrole compound represented by the formula in which each of R -R is, independently, optionally substituted aryl or the like, and may be same or different each other but at least one of them is a hydroxy-aryl group.

摘要： PROBLEM TO BE SOLVED: To obtain recording paper suitable for use in both ink jet and electrophotographic method by applying coating liquid containing an alumina hydrate, a chelating agent, and a cationic substance as in effective components on the support body to be a predetermined value or less in terms of at dry weight. SOLUTION: On the support body surface, applied is coating liquid containing an alumina hydrate, an chelating agent, and a cationic substance as effective components in a manner that it is to be 20g/m less in terms of weight. A water dispersion liquid of 300g prepared by an 18 pts. alumina hydrate, 9 pts. imidazolium compound, 6 pts. ethylenediamine-tetraacetic acid sodium, 17.6 pts. polyacrylamide, and 249.4 pts. water is stirred by a stirrer for 30min. After that, it is dispersed for 30min by TK homomixer at 8,000rpm to obtain coating liquid. The coating liquid is taken out by means of a dropping pipet while being stirred to subsequently be coated and dried on a base weight of 80g/m , 56sec Steckigt sizing degree, 100μm thickness, and 81.2% brightness by Hunter.
