Abstract

Disclosed is an intaglio printing process which comprises (a) forming an intaglio printing plate having groove patterns, (b) filling said groove patterns with an ink, (c) after drying said ink, forming a curable resin layer on the whole surface of the intaglio printing plate, (d) placing a body to be printed thereon without curing said resin layer, (e) curing the curable resin, and (f) stripping the body from the intaglio printing plate to form the ink patterns corresponding to the groove patterns of the intaglio on the body. There are also disclosed processes for producing a color filter, a black matrix and a circuit board.

Claims

1. An intaglio printing process comprising;

(a) forming an intaglio printing plate having groove patterns,

(b) filling said groove patterns with an ink,

(c) after drying said ink, forming a curable resin layer on the whole surface of the intaglio printing plate,

(d) placing a body to be printed thereon without curing said resin layer,

(e) curing the curable resin, and

(f) stripping the body from the intaglio printing plate to form the ink patterns corresponding to the groove patterns of the intaglio on the body.

2. The intaglio printing process according to claim 1, wherein a release layer is formed on the surface of the intaglio printing plate before filling with the ink.

3. The intaglio printing process according to claim 1, wherein the groove patterns of the intaglio printing plate are formed by reactive ion etching.

4. The intaglio printing process according to claim 1, wherein said curable resin is selected from the group consisting of heat-curable resin and photocurable resin.

5. The intaglio printing process according to claim 1, wherein the groove patterns of the intaglio printing plate are formed by ion milling.

6. The intaglio printing process according to claim 1, wherein said ink contains a member selected from the group consisting of an organic pigment and carbon as a main component.

7. The intaglio printing process according to claim 1 wherein said ink is obtained by mixing a member selected from the group consisting of a metal oxide and a metallo-organic compound as a main component, a member selected from the group consisting of an organic compound of a glass frit and an organic compound of a glass component as a sub component and an organic component to form a black matrix pattern.

8. The intaglio printing process according to claim 7 wherein said member selected from the group consisting of a metal oxide and a metallic-organic compound contains a metal of group IB, VB, VIB, VIIB or VIII of the periodic table as a component and the member selected from the group consisting of an organic compound of a glass frit and an organic compound of a glass component contains an element of group IIIA, IVA, VA or VIA of the periodic table.

9. The intaglio printing process according to claim 7 wherein said ink is a noble metal paste.

10. The intaglio printing process according to claim 9 further comprising (g) burning the stripped body.
