    Abstract: A contact lens colorant formulation containing a non-ionic polyalkylene oxide surfactant is applied to a dry hydrophilic contact lens by means of a silicon rubber printing pad to provide a cosmetically acceptable, solid, unblemished covering. This process allows for a solid covering to be placed onto the lens in a single printing step using standard transfer printing devices.

    Abstract: Kontaktlinsen, enthaltend polymere Linsenmaterialien, in denen reaktive Farbstoffe kovalent an Monomereinheiten des Polymergerüsts gebunden wurden, wobei die Farbstoffe reaktive Farbstoffe sind, die geeignet sind zur Bildung von Ätherbindungen mit Cellulose und reaktiv mit Hydroxyl-, Amino-, Amido- oder Mercaptogruppen sind, die in einem Hydrogelpolymeren vorhanden sind, unter Bildung der kovalenten Bindung damit. Die Erfindung ist von besonderem Interesse auf dem Gebiet von «weichen bzw. soft» Kontaktlinsen (Hydrogellinsen).

    Abstract: Disclosed is a reactive dye ink exhibiting excellent ejection stability when used in a printer having an inkjet head for commercial use which requires a high-viscosity ink. The reactive dye ink has excellent storage stability and excellent fixability to textiles. Specifically disclosed is an ink composition containing at least one reactive dye serving as a coloring matter, which also contains water and a compound represented by formula (1) and having an average molecular weight of 340-2,200. (1)

    [In the formula, X 1 , X 2 , X 3 and X 4 independently represent a hydrogen atom or a methyl group; and the sum of j, k, m and n is a number not less than 4 but not more than 40.]
