As has already been in part reported, Hayashi Chemical Industry in Kyoto has carried out test production of a new type fixing agent for ink-jet printing on cotton with pigment ink. The aim of the trial production is to solve a disadvantage that the concentration of colors will be reduced when pigment is ink-jet printed onto cotton, caused by pigments sinking into the fiber structure. Hayashi Chemical Industry, aiming to eliminate the disadvantage, produced two fixing agents which can firmly fix pigments by forming nano-level particle and fine porous coated film.

These two trial products are called High coat FIXA-100 and High coat FIXB-20. They are to fix pigments by the coating and spraying method. They have been tested to fix hues of ink-jet printing on polyester with pigment ink as well.
