Abstract

PURPOSE:To prevent invasion of a developing soln. and generation of electrostatic charge, by using a specified film-forming substance and a chromium complex. CONSTITUTION:The invented recording paper is provided with layers, laminated in succession on the reverse side, consisting of a film-forming substance having at least one group of -OH, -NH2, -COOH, -CONH2, and -SO3H, and a chromium complex having a structure of the formula as shown on the right, in which R is 14-18C satd. aliphatic hydrocarbon, and R'OH stands for water or a liquid alcohol at normal temp. In place of the laminated layers, a mixture layer containing both of the film-forming substance and the complex may be formed. As said substance having -OH or the like group, casein, gelatin, partially saponified polyvinyl acetate, PVA, startch, polyacrylic acid, polystyrenesulfonic acid, cellulose, methyl cellulose, linseed oil, etc. are embodied.

Description

【発明の詳細な説明】 本発明は、湿式現像に用いる静電記録紙の改良に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in electrostatic recording paper used for wet development.

湿式現像に用いる静電記録紙は、裏面から現像液が浸み

これらは高抵抗のものが多く、現像液には濡れにくいが
静電気を帯び易く、裏面が汚れるとか、表面と摩擦帯電
して画像面を汚したりする欠点がある。The electrostatic recording paper used for wet development had a dark appearance due to the developer seeping in from the back side. Therefore, some types of electrostatic recording paper have an oil repellent such as a fluorine compound or a silicone compound coated on the back side. however,
Many of these materials have high resistance, and although they are difficult to wet with the developer, they are easily charged with static electricity, and have the disadvantage that the back surface becomes dirty or the image surface becomes smudged due to frictional charging with the front surface.

本発明はこの点を改善せんとするもので、現像液の浸み
込みを防止し、静電気の発生も防止してコピーイメージ
を高めることを目的とするものである。The present invention aims to improve this point, and aims to improve the copy image by preventing the developer from penetrating and the generation of static electricity.

とする湿式現像に用いる静電記録紙である。That is, in the present invention, -OR, -NH4I-C
At least 1 of OOH, -CONH2, -5o3H
This electrostatic recording paper is used for wet development and is characterized by being formed by sequentially laminating a substance having various types of groups and a chromium complex having the following structure, or by providing a mixed layer of both.

めることができる。R By adopting such a configuration, the present invention exerts an oil repellent effect through the reaction between a substance having a group such as 10H and the above-mentioned Cr complex, and prevents the developer from penetrating from the back side. Moreover, the layer obtained by the present invention has a lower resistance (approximately 10 Ω) than conventional fluorine compounds, silicon compounds, etc.
