Ink-jet recording sheet

An ink-jet recording sheet comprising a support and an ink-absorbable layer is disclosed. The ink-absorbable layer is a void layer containing fine inorganic particles having a dispersion degree of no more than 2 and a hydrophilic binder. The ink-jet recording sheet has a specular gloss specified by JIS Z8741, of at least 20 percent at 60 degrees of the surface of said ink absorbable layer, and exhibits the specular gloss such that 60-degree specular gloss of an ink-recorded part is 3 percent more than that of a nonink-recorded part.

What is claimed is:

1. An ink-jet recording sheet comprising a support having thereon an ink-absorbable layer which is composed of at least two void layers containing inorganic particles having adispersion degree of no more than 2 and a hydrophilic binder, wherein at least one void layer, except for the uppermost void layer, of the void layers has organic compound particles having a relatively large particle diameter and the ink-jet recordingsheet has a specular gloss specified by JIS Z8741, of at least 20 percent at 60 degrees of the surface of said ink absorbable layer, and exhibits the specular gloss such that 60-degree specular gloss of an ink-recorded part is 3 percent more than that ofa nonink-recorded part.

2. An ink-jet recording sheet comprising a support having thereon an ink-absorbable layer which is composed of at least two void layers containing inorganic particles having a dispersion degree of no more than 2, polyvinyl alcohol and ahardener, wherein at least one void layer, except for the uppermost void layer, of the void layers has organic compound particles having a relatively large particle diameter and the ink-jet recording sheet has a specular gloss of at least 20 percent at60 degrees of the surface of said ink absorbable layer, and exhibits the specular gloss such that 60-degree specular gloss of an ink-recorded part is 3 percent not less than that of a nonink-recorded part.

3. An ink-jet recording sheet of claim 2 wherein the support is water-resistant.

4. An ink-jet recording sheet of claim 2 wherein the inorganic particles are silica having an average particle diameter of no more than 100 nm.

5. An ink-jet recording sheet of claim 2 wherein the void layer contains a hardener.

6. An ink-jet recording sheet of claim 5 wherein the hardener is boric acids or salts thereof.

7. An ink-jet recording sheet of claim 2 wherein the support has a specular gloss of 20 to 80 percent.

8. An ink-jet recording sheet of claim 3 wherein the support is translucent polyester film, opaque polyolefin resin film or paper laminated with polyethylene on both surfaces of a paper substrate.

9. An ink-jet recording sheet of claim 8 wherein the support is paper laminated with polyethylene on both surfaces of a paper substrate.

10. An ink-jet recording sheet of claim 1 wherein the ink-jet recording sheet exhibits the specular gloss such that 60-degree specular gloss of an ink-recorded part is 3 to 20 percent more than that of a nonink-recorded part.

11. An ink-jet recording sheet of claim 10 wherein the ink-jet recording sheet exhibits the specular gloss such that 60-degree specular gloss of an ink-recorded part is 5 to 15 percent more than that of a nonink-recorded part.

12. An ink-jet recording sheet of claim 1 wherein the hydrophilic binder is polyvinyl alcohol.

13. The ink-jet recording sheet of claim 2 wherein the inorganic particles have an average diameter of no more than 100 nm.

14. The ink jet recording sheet of claim 13 wherein the support is water-resistant.

15. The ink-jet recording sheet of claim 13 wherein the hardener is boric acids or salts thereof.

16. The ink-jet recording sheet of claim 13 wherein the support has a specular gloss of 20 to 80 percent.

17. The ink-jet recording sheet of claim 13 comprising the inorganic particles in an amount of 3 to 50 g per 1 m.sup.2 of the sheet.

18. The ink-jet recording sheet of claim 17 comprising the polyvinyl alcohol in an amount of 0.5 to 10 g per 1 m.sup.2 of the sheet.

19. The ink-jet recording sheet of claim 13 wherein the ink-jet recording sheet exhibits the specular gloss such that 60-degree specular gloss of an ink-recorded part is 5 to 15 percent more than that of a nonink-recorded part.

20. An ink-jet recording sheet of claim 1 wherein the support is water-resistant, the hardener is boric acids or salts thereof, and the inorganic particles are silica.

21. The ink-jet recording sheet of claim 1, wherein the relatively large particle diameter is 1.0 .mu.m to 5.0 .mu.m.

22. The ink-jet recording sheet of claim 2, wherein the relatively large particle diameter is 1.0 .mu.m to 5.0 .mu.m.
