no. 1 approach

[0087] According to a first embodiment of the method of the invention, the pattern of electroless deposition catalyst consists of continuous areas of electroless deposition catalyst.

no. 2 approach

[0088] According to a second embodiment of the method of the invention, the contact printing method comprises the steps of applying an electroless deposition catalyst pattern to an intermediate plate or roll through a hydrophilic phase, and transferring the electroless deposition catalyst pattern from the intermediate plate or roll to a receiver. on the medium.

no. 3 approach

[0089] According to a third embodiment of the method of the invention, the contact printing method comprises the steps of applying the pattern of electroless deposition catalyst to the printing master through the hydrophilic phase and transferring the pattern of electroless deposition catalyst from the printing master to the receiving medium.

[0090] Preferred printing techniques include, conventional offset printing using an aqueous fountain solution and an oleophilic ink, reverse offset printing using a hydrocarbon or mineral oil as a fountain medium and a hydrophilic ink, using a single fluid ink Fountain solution in emulsion or ink) offset printing, and water-based offset printing using water-based water-free offset printing inks.

[0091] Offset printing has the advantage of printing smooth continuous areas at very high speed and high resolution. Compared to, for example, screen printing, there is very little evaporation of solvent and / or water from the offset printing f...

Abstract

A process comprising the step of: contact printing a pattern of an electroless deposition catalyst via a hydrophilic phase to a receiving medium, wherein said electroless deposition catalyst requires no activation prior to electroless deposition.

Description

field of invention [0001] The present invention relates to a method for printing electroless deposition catalyst pattern by hydrophilic phase contact. Background of the invention [0002] In addition to printing with conventional colored inks, printing is also increasingly used to apply patterns of functional substances. In the case of functional substances which are only soluble or dispersible in aqueous media, problems may arise with their incorporation into oleophilic inks. [0003] WO 01 / 88958 discloses in claim 1 a method of forming a pattern of a functional substance on a substrate, the method comprising: applying a first pattern of a first substance to the substrate; and applying a second a functional substance is applied to the substrate and the first substance, wherein the first substance, the second functional substance and the substrate interact to spontaneously form a second pattern of the second functional substance on the substrate, And thus form a pattern of...
