INVERSION PRINTING INK, INVERSION PRINTING METHOD USING IT, LIQUID CRYSTAL COLOR FILTER, AND MANUFACTURING METHOD OF LIQUID CRYSTAL COLOR FILTER

摘要

PROBLEM TO BE SOLVED: To provide ink good in wettability of the ink on the surface of a silicone blanket and suitable for use in inversion printing method, an inversion printing method with the ink, and a liquid crystal color filter having a high quality color filter layer and a black matrix, and its manufacturing method.

SOLUTION: This inversion printing ink is prepared by compounding a binder resin, a coloring agent, a polysiloxane denaturalized by a polyether or something with a denaturalization rate D of 0.01-20%, and a solvent, and viscosityη(23°C) is made 1-20 mPa s, and the compounding quantity of the denaturalized polysiloxane is made to 0.01-5 pts.wt. to 100 pts.wt. binder resin. Using this inversion printing ink and an inversion printing method, the color filter layer, the black matrix, etc., of the liquid crystal color filter are printed.
