Abstract

Provided is a composition for a printing medium and a printing medium that can be suitably used for a plurality of printing methods, including a plurality of plateless printing methods such as thermal transfer printing, electrophotographic printing, and inkjet printing methods. A coating layer is provided on at least one surface of a support body, and includes (a) a cationic urethane-based resin, (b) an olefin copolymer emulsion, and (c) an ethyleneimine-based resin. The solid mass of the coating layer on one surface of the support body may be 0.01-5 g/m 2 .

First claim

What is claimed is:

1. A printing medium composition comprising (a) a cationic urethane-based resin, (b) 10-400 pts. mass of an olefin copolymer emulsion, and (c) 1-60 pts. mass of an ethyleneimine-based resin, relative to 100 pts. mass of (a) the cationic urethane-based resin.

2. A printing medium comprising:
a coating layer that is provided on at least one surface of a support body and includes a printing medium composition comprising (a) a cationic urethane-based resin, (b) an olefin copolymer emulsion, and (c) an ethyleneimine-based resin, wherein
solid mass of the coating layer on one surface is greater than or equal to 0.01 g/m 2 and less than 5 g/m 2 .

3. The printing medium according to claim 2 , wherein
the coating layer further includes (d) an antistatic agent.

4. The printing medium according to claim 3 , wherein
(d) the antistatic agent includes at least one of an acrylic resin containing ternary nitrogen and an acrylic resin containing quaternary nitrogen.

5. The printing medium according to claim 2 , wherein
the coating layer further includes (e) a cross-linking agent.

6. The printing medium according to claim 5 , wherein
(e) the cross-linking agent includes an epichlorohydrin additive of polyamine polyamide.

7. The printing medium according to claim 2 , wherein
the support body is a film layer including a thermoplastic resin.

8. The printing medium according to claim 7 , wherein
the thermoplastic resin includes a polyolefin-based resin.

9. The printing medium according to claim 7 , wherein
the film layer including the thermoplastic resin further includes at least one of inorganic particles and an organic filler.

10. The printing medium according to claim 9 , wherein
the inorganic particles include calcium carbonate with an average particle diameter of 0.01-15 μm.

11. The printing medium according to claim 7 , wherein
the film layer including the thermoplastic resin is stretched in a direction of at least one axis.
