【発明の詳細な説明】 〔産業上の利用分野〕 本発明は減感インキ組成物に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to desensitizing ink compositions.

(積層状態とせずに両層混然一体となした単一層塗設の
セルフコンテインド紙も発表されている)。It usually consists basically of a top paper coated with microcapsules containing a solution of an electron-donating colorless dye and a bottom paper coated with an electron-accepting color developer. The colorless dye is released and encounters the color developer on the base paper to develop color and produce a visible copy image. In addition, an inner paper (a paper-like support with microcapsules containing a colorless dye solution on one side and a color developer fully coated on the other side) is used to serve as both the top paper and the bottom paper. By inserting it between the two, you can make multiple copies. In addition, if a layer of microcapsules containing a colorless dye solution and a layer of a color developer are laminated and coated on one side of a support, a pressure-sensitive color image can be obtained even with a single sheet of paper, which can be used as self-contained paper. (Self-contained paper with a single layer coating, in which both layers are mixed together without being laminated, has also been announced).

げなければならない。In order to actually apply desensitizing ink to the developing surface, it is necessary to improve the accuracy of repeated work (improve registration), improve the surface quality of the lunar surface, improve the accuracy of the amount of adhesion, and diversify form designs. Various printing methods (flexo/gravure printing, letterpress printing, offset printing, silk screen printing, etc.) are often used for the purpose of improving work efficiency, etc. Therefore, it is necessary to use inks that are compatible with these printing methods. A desensitizing agent and other auxiliary materials, additives, etc. are blended and put into practical use in the form of a composition. (A composition formulated for printing in this way is called a desensitizing ink.) For this reason, in addition to the ability to prevent color development and erasing, that is, desensitizing ability, the desensitizing agent has various properties. It must be mentioned that a desensitized ink with printing suitability depending on the printing method can be prepared.

Another problem is that the dampening liquid is taken into the desensitized ink area of the printing plate, and the desensitized ink gradually diffuses and migrates to areas where color development is required, resulting in a decrease in color development performance in that area or disappearance. Ta. Furthermore, if the supply of the dampening liquid is reduced, the desensitized ink will adhere to the entire area where coloring is required.

加え3本ロールミルによりインキを調整した。Example 3 Components other than the pigment were mixed and dissolved, and then the pigment of Example 1 was added to prepare an ink using a three-roll mill.
このインキを用いる以外は実施例2をくりかえし、紫外
線硬化への影響もなく、同様な良好な結果を得た。Example 2 was repeated except that this ink was used, and similar good results were obtained without any effect on ultraviolet curing.
実施例4
実施例2の印刷版を市販の銀塩タイプのダイレクト印刷
版(三菱シルバーマスター)、給湿液として三菱シルバ
ーマスター専用給湿液を用いる以外は実施例2をくりか
えし、良好な結果金得た。Example 4 Example 2 was repeated except that the printing plate of Example 2 was used as a commercially available silver salt type direct printing plate (Mitsubishi Silver Master) and a dampening liquid exclusively for Mitsubishi Silver Master was used as the dampening liquid. Good results were obtained. Obtained.
