Abstract

The present invention provides a resin-based ink recorded body having high transparency, high definition, free from bleeding and having a high film strength of an ink. An ink recording member of the present invention includes a substrate containing an acrylic resin and a plant oil derived from a fatty acid having hydroxyl and carboxyl group blended to the acrylic resin, and an ink fixing film composed of a hydrophilic resin and provided on at least one main face of the substrate. An ink printed pattern is provided on the film.

First claim

The invention claimed is:

1. An ink recording member comprising:
a substrate comprising an acrylic resin and a plant oil blended to said acrylic resin, said plant oil being derived from a fatty acid having hydroxyl group and carboxyl group; and
a ink fixing film provided on an at least one main face of said substrate and comprising a hydrophilic resin.

2. The ink recording member of claim 1 , wherein said acrylic resin comprises an acrylic block copolymer.

3. The ink recording member of claim 1 , wherein said plant oil comprises castor oil or a derivative thereof.

4. The ink recording member of claim 1 , wherein an adhesive strength between said substrate and said ink fixing film is 0.3 to 10 N.

5. The ink recording member of claim 1 , wherein a storage modulus (E′) at a temperature of 10° C. to 40° C.±3 is 10000 Pa to 100 MPa, in a measurement of dynamic viscoelasticity (tension mode, 11 Hz) of said substrate.

6. The ink recording member of claim 1 , wherein a peak temperature of tan δ of a soft segment corresponding to transition from glass state to rubber state is in a range of −80° C. to +50° C., in a measurement of dynamic viscoelasticity (tension mode, 11 Hz) of said substrate.

7. The ink recording member of claim 1 , wherein said substrate has a shore hardness (ASTM D2240) in a range of 10 to 90 at a temperature of 10° C. to 40° C.

8. The ink recording member of claim 1 , wherein said substrate has a self-adhesiveness of 0.5 to 10 N.

9. The ink recording member of claim 1 , wherein said hydrophilic resin comprises a water soluble resin.

10. The ink recording member of claim 1 , wherein said hydrophilic resin has a contact angle with respect to water of 3° to 60°.

11. The ink recording member of claim 1 , having a total light transmittance of 70 percent or higher and a haze value of 30 percent or lower.

12. The ink recording member of claim 1 , further comprising a supporting body joined with said substrate.

13. An ink recorded body, comprising said ink recording member of claim 1 , and an ink printed pattern fixed on said ink fixing film.

14. The ink recorded body of claim 13 , wherein said ink comprises at least one of a water soluble pigment ink and a water soluble dye ink.

15. A laminated ink recorded body comprising a plurality of said ink recorded bodies of claim 13 , wherein said ink recorded bodies are laminated.
