Background of invention

Modern non-aqueous ink for writing instruments are largely homogeneous in nature; that is, the dye is dissolved in the liquid medium of the ink. Heterogeneous non-aqueous ink currently exist, but they constitute a very small part of the total market nonaqueous writing instruments and limited to a very narrow range of colors, such as black, blue, red and green. Specialists in the development of formulations of ink for writing instruments need to move forward with the aim of expanding the range of dyes up to metal, photochromic, thermochromic, pearl, inorganic, organic, fluorescent and other. Many, if not all, of these desirable dyes do not dissolve in the currently used solvents.

The production of lithographic printing inks differs from receiving ink for ink work. In the case of lithographic printing inks, the problem lies in the fact that the paint was dry immediately after printing. For example, developing paint chemists usually want the paint has dried or hardened as quickly as possible so that the printed material can be moved and brochureware (for example, in a magazine or a book) without erasing or smearing of ink from the printed sheet. So enter the additives for polymerization of alkyd resins or for interaction with air (for example, use of metallic driers, such as cobalt, manganese, naphthenate of lead introduced into the paint after paint application. This problem differs from the problem in the case of the ink for ink work, which is the protection of the ink from drying when naheed the Institute in writing the tool. The present invention is directed to satisfying this need.

There is a need in the ink for a writing instrument containing a lot of a variety of insoluble dyes.
