Abstract

This printing material has: a substrate; an ink-accepting layer that is disposed on the substrate and is the cured product of a resin composition; and an ink layer that is disposed on the ink-accepting layer and is the cured product of an active-light-ray-curable cationic polymerizable ink. The ink-accepting layer is impermeable with respect to the active-light-ray-curable cationic polymerizable ink. Also, the active-light-ray-curable cationic polymerizable ink contains: a cationic polymerizable compound; 0.5-10.0 mass % of an epoxy-group-containing silane coupling agent; 10-50 mass % of a hydroxyl-group-containing oxetane compound; and a photoinitiator.

First claim

1 . A printed material comprising:
a base material being a metallic base material or a ceramic base material; an ink-receiving layer disposed on the base material and formed of a cured product of a resin composition; and an ink layer disposed on the ink-receiving layer and formed of a cured product of a cationic actinic radiation-curable ink, wherein: the cationic actinic radiation-curable ink contains a cationically-polymerizable compound, an epoxy group-containing silane coupling agent, a hydroxyl group-containing oxetane compound and a photopolymerization initiator, a content of the epoxy group-containing silane coupling agent in the cationic actinic radiation-curable ink is in a range of 0.5 to 10.0 mass %, and a content of the hydroxyl group-containing oxetane compound in the cationic actinic radiation-curable ink is in a range of 10 to 50 mass %.

2 . The printed material according to claim 1 , wherein the ink-receiving layer is impenetrable to the cationic actinic radiation-curable ink.

3 . The printed material according to claim 1 , wherein a surface of the ink-receiving layer has an arithmetic average roughness Ra in a range of 400 to 3,000 nm as measured in accordance with JIS B 0601.

4 . The printed material according to claim 1 , wherein the resin composition contains a polyester and a melamine resin, or contains a polyester and a urethane resin, or contains a polyester, a melamine resin and a urethane resin.

5 . The printed material according to claim 1 , wherein the hydroxyl group-containing oxetane compound is 3-ethyl-3-hydroxymethyloxetane.

6 . The printed material according to claim 2 , wherein a surface of the ink-receiving layer has an arithmetic average roughness Ra in a range of 400 to 3,000 nm as measured in accordance with JIS B 0601.

7 . The printed material according to claim 2 , wherein the resin composition contains a polyester and a melamine resin, or contains a polyester and a urethane resin, or contains a polyester, a melamine resin and a urethane resin.

8 . The printed material according to claim 3 , wherein the resin composition contains a polyester and a melamine resin, or contains a polyester and a urethane resin, or contains a polyester, a melamine resin and a urethane resin.

9 . The printed material according to claim 6 , wherein the resin composition contains a polyester and a melamine resin, or contains a polyester and a urethane resin, or contains a polyester, a melamine resin and a urethane resin.

10 . The printed material according to claim 2 , wherein the hydroxyl group-containing oxetane compound is 3-ethyl-3-hydroxymethyloxetane.

11 . The printed material according to claim 3 , wherein the hydroxyl group-containing oxetane compound is 3-ethyl-3-hydroxymethyloxetane.

12 . The printed material according to claim 4 , wherein the hydroxyl group-containing oxetane compound is 3-ethyl-3-hydroxymethyloxetane.

13 . The printed material according to claim 6 , wherein the hydroxyl group-containing oxetane compound is 3-ethyl-3-hydroxymethyloxetane.

14 . The printed material according to claim 7 , wherein the hydroxyl group-containing oxetane compound is 3-ethyl-3-hydroxymethyloxetane.

15 . The printed material according to claim 8 , wherein the hydroxyl group-containing oxetane compound is 3-ethyl-3-hydroxymethyloxetane.

16 . The printed material according to claim 9 , wherein the hydroxyl group-containing oxetane compound is 3-ethyl-3-hydroxymethyloxetane.
