Abstract

Provided is a medium including: a base material; and a print section over the base material, wherein the print section contains an alcohol compound having a boiling point of 180 degrees C. or higher and a viscosity of 30 mPa·s or lower at 25 degrees C., and wherein the medium includes an adhesive section containing an isocyanate compound.

Claims

1. A medium comprising:

a base material; and

a print section over the base material,

wherein the print section comprises an alcohol compound having a boiling point of 180 degrees C. or higher and a viscosity of 30 mPa·

s or lower at 25 degrees C., and

wherein the medium comprises an adhesive section that comprises an isocyanate compound.

2. The medium according to claim 1,

wherein the print section is a section formed through cross-linking between the isocyanate compound and the alcohol compound.

3. The medium according to claim 1,

wherein the adhesive section is a section to be provided over the base material, and the print section is a section to be formed over the adhesive section along with the providing of the adhesive section.

4. The medium according to claim 1,
