The present invention relates to a method of printing on substrates in sheet form, for example on paper, thermoplastic film or fibrous textile materials, the process of inkjet printing and the inks used in this way.

In our days there is a high demand on the composition of the ink for use in inkjet printing, in particular for use in multi-color or print. So, for example, attach great importance to the fact that the dye-based ink as possible corresponded to the three primary colors: yellow, blue and purple. The selection of suitable dyes is limited not only by the purity of color and the target color reproduction brightness, but also the required shade. Although there are a large number of yellow acid dyes and direct dyes, for the mentioned reasons for use in inkjet printing of them are acceptable only an insignificant number. To control the paint against the desired shade in the famous yellow ink for inkjet printers often include a mixture of yellow dyes of different types, for example a mixture of Golden yellow direct dyes with lemon-yellow dye. However, this lemon yellow dyes of the inherent disadvantage that when used in combination with blue dye, they are ten is enciu to catalytic bleaching in the field of green, and it is noticeable unwanted effects in a yellow ink for inkjet printing, including lemon yellow dyes.

Dyes suitable for use in inkjet printing, should also be considered to obtain prints having the properties of good siteprotect, good water resistance and high dye saturation, and they must show good solubility in the solvent-based paint. The ink must also be stable in storage and does not form any precipitate during long-term storage and, when used in ink jet printing devices, they must guarantee the high reliability of the printing device.

For this reason, there is a continuing need to develop a method of inkjet printing, which uses enhanced yellow ink composition and which is free from the above disadvantages or they are inherent only to a small extent.
