Abstract

PURPOSE:To obtain the entitled correcting agent capable of correcting an image rapidly and perfectly without disclosing the corrected parts again after forming a large number of prints, and not deteriorating in correction capability during long period storage, by incorporating a specified s-triazine. CONSTITUTION:An agent for correcting a printing plate is obtained by dissolving into an org. solvent and/or water 0.1-20wt% s-triazine compd. represented by the shown formula in which R is H or -R'-COOH, and R' is alkylene or arylene. This agent is involatile, stable, nonodorant, and nontoxic, and it can correct an image rapidly and perfectly, and since ink is not transferred on the corrected part even by strongly rubbing this part, a large number of prints can be made.

DETAILED DESCRIPTION OF THE INVENTION In an offset printing plate using an ink-receiving image of the present invention (・maω;rIiii), an unnecessary portion of a silver image formed on the offset printing plate is converted to hydrophilicity. The invention relates to an image modifying agent for offset printing plates which eliminates the ink receptivity of the printing plate, and more particularly, it relates to an image modifying agent for offset printing plates which eliminates the ink receptivity, and more particularly, which removes unwanted portions of the silver image on the printing plate (offsets formed by photographic or physical methods). This process involves treating the surface with a specific treatment agent at any stage in the process to completely make it hydrophilic and eliminate ink receptivity without causing any damage to printing characteristics, substrates, etc. Since such processing is usually called "correction" in the printing field, the present inventors will follow this term hereinafter.

In general, the areas that need to be corrected in printing master plates produced by photolithography include those that are present in the original copy, those that occur during exposure, and other irregularities.
There are some that occur during the development process.

For example, if there are unnecessary images in the copy original, if there are dust and dirt particles, fingerprints or other stains, or if the original is made by gluing together different originals. In some cases, shadows may appear during exposure. In order to obtain good printed matter, all of these points must be corrected during the plate-making and printing stages. Generally speaking, correction operations are essential, and it is desirable to be able to perform necessary corrections at any stage of the plate-making and printing processes.

A number of attempts have been made to correct unwanted images in offset printing plates by utilizing silver color as ink receptivity. For example, hydrophilic metal salts, rubber, latex, gelatin, or other hydrophilic polymers may be applied to the silver image by precipitating pigments, or mechanically removing the silver image using an eraser, knife, etc. Metallic silver in the image area is removed by treatment with a so-called silver image bleach-fixing composition containing an oxidizing agent such as dichromate or red blood salt, and sulfite or thiosulfate. However, it is difficult to completely correct the oleophilic image using the method described above.The lipophilic image may be exposed again during printing, causing other problems such as smudges, and the processing time may be too long. Not only does this have disadvantages, such as lowering work efficiency, or the stability of the correction fluid itself is insufficient, resulting in a decline in performance during storage, but also - after the start of support printing, that is, silver images. It has been practically difficult to erase, ie, correct, the image after forming an ink film thereon.

However, despite their excellent modifying ability, these modifiers still have drawbacks. The reason is that the mercazot compound has a characteristic bad odor, is easily oxidized like raw cysteine, and is unstable when used as a correction solution.Furthermore, since it is a strongly acidic solution, it has no adverse effects on the human body. However, the ease of handling and workability are reduced.
