あるという問題点があった。However, these fluorescent ink compositions for jet printing can form an image of high fluorescence emission on the surface of a printing material having no liquid absorbing property. For example, when printing on an ink-jet printer, the fluorescent dye in the ink composition permeates and diffuses into the deep part of the printing material together with the solvent when printing on an ink-receiving printing material surface such as paper or fabric. It is operationally or economically difficult to increase the concentration of the fluorescent dye on the surface, which causes a problem that the fluorescence emission intensity on the surface of the printing medium is insufficient. In particular, when the liquid-absorptive printing material is colored with black or the like, there is a problem that the shortage of the fluorescence emission intensity on the surface of the printing material is remarkable.

組成物を提供することを目的とする。The present invention solves the problems of the conventional fluorescent ink composition for jet printing, in which a larger amount of the fluorescent dye remains on the surface of the printing medium so that the amount of the fluorescent dye is reduced. It is an object of the present invention to provide a fluorescent ink composition for jet printing which can increase the concentration of a fluorescent dye and form an image with high fluorescence emission intensity.

られるという知見を得て本発明を完成した。Means for Solving the Problems As a result of various studies for solving the above problems, the present inventors have found that transparent solid fine particles , particularly the features described below, are contained in the fluorescent ink composition for jet printing.
By including certain transparent solid fine particles , these fine particles adhere to the surface without penetrating deep into the printing medium, and the fluorescent dye is added to the ink composition before jet printing (that is, in the ink composition before application). Or, during jet printing (ie, when the ink composition is applied to the surface of the printing medium and penetrates into the deep part of the printing medium), the fine particles are adsorbed on the surface of the printing medium, so that penetration into the deep part of the printing medium is reduced. As a result, the inventors have found that the concentration of the fluorescent dye on the surface of the printing medium is increased, and an image having a high fluorescence emission intensity is obtained, thereby completing the present invention.

For example, in the case where fluorescent light is not emitted with visible light, but it is desired to emit fluorescent light when irradiated with infrared light, a fluorescent dye suitable for this may be appropriately selected.

IR-125, 132, 140, HIDC Iodide and the like are typical examples. Considering the storage stability of the fluorescent ink composition for jet printing, it is desirable that these fluorescent dyes be dissolved or stably dispersed in water. However, even hydrophobic dyes are used by adsorbing them to transparent solid fine particles in advance. It is possible.

染料濃度が高くなるのである。The transparent solid fine particles used in the present invention are blended in order to increase the concentration of the fluorescent dye on the surface of the printing medium and to obtain an image having a high fluorescence emission intensity. That is, in the case of a liquid-absorbing printing material, the fluorescent dye easily penetrates and diffuses into the deep portion of the printing material together with the solvent, but when transparent solid fine particles are blended in the fluorescent ink composition for jet printing, these fine particles are used. Remains on the surface without penetrating into the deep part of the printing medium, and the fine particles remaining on the surface of the printing medium adsorb the fluorescent dye before or during jet printing, and the fluorescent dye is absorbed into the deep part of the printing medium. The penetration is suppressed, and as a result, the concentration of the fluorescent dye on the surface of the printing medium is increased.

However, those which do not transmit light are unsuitable for the present invention because the fluorescence emission intensity is reduced and the printed material is stained. The particle diameter of the transparent solid fine particles is preferably 1 μm or less so as not to cause nozzle clogging of a jet printer, and also preferably 0.01 to 0 in consideration of the fact that the particles tend to remain on the surface of the printing medium. 0.5 μm .
