Abstract

The present invention relates to a method of manufacturing a decorative building board, including: ejecting active ray-curable ink from an ink jet recording head onto a building board that includes a base material selected from a metallic base material and a ceramic base material and an ink receiving layer arranged on the base material, the ink receiving layer being obtained by curing a resin composition and having an arithmetic average roughness (Ra) specified under JIS B 0601:2001 of from 0.4 μm to 3 μm, to thereby perform printing on the ink receiving layer; and irradiating the active ray-curable ink with an active ray from 2.2 seconds to 30 seconds after the active ray-curable ink lands on the ink receiving layer.

First claim

The invention claimed is:

1. A method of manufacturing a decorative building board, comprising:
ejecting active ray-curable ink from an ink jet recording head onto a building board that includes a base material selected from a metallic base material and a ceramic base material and an ink receiving layer arranged on the base material, the ink receiving layer being obtained by curing a resin composition and having an arithmetic average roughness (Ra) specified under JIS B 0601:2001 of from 0.4 μm to 3 μm, to thereby perform printing on the ink receiving layer; and
irradiating the active ray-curable ink with an active ray from 2.2 seconds to 30 seconds after the active ray-curable ink lands on the ink receiving layer.

2. A method of manufacturing a decorative building board according to claim 1 , wherein the ink receiving layer is non-permeable with respect to the active ray-curable ink.

3. A method of manufacturing a decorative building board according to claim 1 , wherein the active ray-curable ink comprises active ray-curable cationically polymerizable ink.

4. A method of manufacturing a decorative building board according to claim 1 , wherein a volume of one drop of the ink that lands on a surface of the ink receiving layer is 10 picoliters to less than 45 picoliters.

5. A method of manufacturing a decorative building board according to claim 1 , wherein an initial speed of an ejected ink drop of the active ray-curable ink is from 3 m/sec to 9 m/sec.

6. A method of manufacturing a decorative building board according to claim 1 , wherein the resin composition contains solid particles.

7. A method of manufacturing a decorative building board according to claim 6 , wherein the solid particles comprise inorganic particles.

8. A method of manufacturing a decorative building board according to claim 7 , wherein the inorganic particles comprise one or more kinds selected from the group consisting of silica, barium sulfate, talc, calcium carbonate, mica, glass beads, and glass flakes.

9. A method of manufacturing a decorative building board according to claim 6 , wherein the solid particles have an average particle diameter of from 4 μm to 80 μm.
