Abstract

A recording medium is provided which comprises an ink-transporting layer and ink-retaining layer. The ink-transporting layer contains in combination a surfactant and/or a penetrant and a material having the property of fixing a colorant contained in an ink.

Claims

1. A recording medium comprising a non-porous ink-retaining layer and a porous ink-transporting layer laminated on a substrate in this order, said ink-transporting layer comprising (i) at least one of a surfactant and a penetrant, and (ii) a material which is capable of fixing a colorant contained in an ink, which colorant remains in said ink-transporting layer after application of said ink to said recording medium.

2. The recording medium of claim 1, wherein said ink-transporting layer contains in combination at least one of the surfactant and the penetrant, and the material having the property of fixing the colorant contained in the ink, in the proportion of from 1:

100 to 50;

1.

3. The recording medium of claim 1, wherein said ink-transporting layer contains in combination at least one of the surfactant and the penetrant, and the material having the property of fixing the colorant contained in the ink, in the proportion of from 1:

50 to 5;

1.

4. The recording medium of claim 1, wherein said ink-transporting layer contains the material having the property of fixing the colorant contained in the ink, in an amount of from 0.05% by weight or more.

5. The recording medium of claim 1, wherein said ink-transporting layer containing the material having the property of fixing the colorant contained in the ink, in an amount of 0.1% by weight or more.

6. The recording medium of claim 1, wherein said material having the property of fixing the colorant contained in the ink is a nonvolatile compound having a primary, secondary or tertiary amino group, or a quaternary ammonium group.

7. The recording medium of claim 1, wherein said material having the property of fixing the colorant contained in the ink is a salt of a polyvalent metal.

8. The recording medium according to claim 1, wherein said substrate is light-transmissive.

9. The recording medium of claim 1, wherein said ink-transporting layer is light-diffusive.

10. The recording medium of claim 1, wherein said ink-retaining layer is light-transmissive.

11. The recording medium of claim 1, wherein said ink-transporting layer is liquid permeable.

12. The recording medium of claim 1, wherein said ink-retaining layer has a higher absorbability than said ink-transporting layer.

13. A recording medium comprising a non-porous ink-retaining layer and a porous ink-transporting layer laminated on a substrate in this order, said ink-transporting layer comprising (i) at least one of a surfactant and a penetrant, and (ii) a material which is capable of fixing a colorant contained in an ink, which colorant remains in said ink-transporting layer and said ink-retaining layer containing said material or another material capable of fixing the colorant contained in the ink.

14. The recording medium of claim 13, wherein said ink-transporting layer contains in combination at least one of the surfactant and the penetrant, and the material having the property of fixing the colorant contained in the ink, in the proportion of from 1:

100 to 50;

1.

15. The recording medium of claim 13, wherein said ink-transporting layer contains in combination at least one of the surfactant and the penetrant, and the material having the property of fixing the colorant contained in the ink, in the proportion of from 1:

50 to 5;

1.

16. The recording medium of claim 13, wherein said ink-transporting layer contains the material having the property of fixing the colorant contained in the ink, in an amount of from 0.05% by weight or more.

17. The recording medium of claim 13, wherein said ink-retaining layer contains the material having the property of fixing the colorant contained in the ink, in an amount of from 0.5 to 50% by weight.

18. The recording medium of claim 13, wherein said material having the property of fixing the colorant contained in the ink is a nonvolatile compound having a primary, secondary or tertiary amino group or a quaternary ammonium group.

19. The recording medium of claim 13, wherein said material having the property of fixing the colorant contained in the ink is a salt of a polyvalent metal.

20. The recording medium of claim 13, wherein said substrate is light-transmissive.

21. The recording medium of claim 13, wherein said ink-transporting layer is light-diffusive.

22. The recording medium of claim 13, wherein said ink-retaining layers is light-transmissive.

23. The recording medium of claim 13, wherein said ink-transporting layer is liquid permeable.

24. The recording medium of claim 13, wherein said ink-retaining layer has a higher absorbability than said ink-transporting layer.

25. A recording medium comprising a non-porous ink-retaining layer and a porous ink-transporting layer laminated on a substrate in this order, said ink-transporting layer substantially comprising (i) a particulate material, (ii) a binder and (iii) at least one of a surfactant and a penetrant, and wherein said particulate material or said binder is capable of fixing a colorant contained in an ink, which colorant remains in said ink-transporting layer.

26. The recording medium of claim 25, wherein said ink-transporting layer contains in combination at least one of the surfactant and the penetrant, and the material having the property of fixing the colorant contained in the ink, in the proportion of from 1:

100 to 50;

1.

27. The recording medium of claim 25, wherein said ink-transporting layer contains in combination at least one of the surfactant and the penetrant, and the material having the property of fixing the colorant contained in the ink, in the proportion of from 1:

50 to 5;

1.

28. The recording medium of claim 25, wherein said material having the property of fixing the colorant contained in the ink comprises the particulate material or binder having been subjected to a cationization treatment.

29. The recording medium of claim 25, wherein said ink-retaining layer contains the material having the property of fixing the colorant contained in the ink.

30. The recording medium of claim 25, wherein said substrate is light-transmissive.
