Claims
- 1. An ink-jet recording sheet comprising:
a support and an ink-absorbable layer provided thereon, the ink-absorbable layer comprising a plurality of void layers containing first particles having a dispersion degree of no more than 2 and a hydrophilic binder, wherein at least one of the void layers, except for the uppermost void layer to the support, comprises second particles having a refractive index higher than that of the first particles, so that the ink-jet recording sheet has a specular gloss of at least 20 percent at 60 degrees of the surface of the ink-absorbable layer, and the ink-jet recording sheet 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.
- 2. The ink-jet recording sheet of claim 1, wherein the support is water resistant.
- 3. The ink-jet recording sheet of claim 1, wherein the first particles are silica having an average particle diameter of no more than 100 nm.
- 4. The ink-jet recording sheet of claim 1, wherein the hydrophilic binder is polyvinyl alcohol.
- 5. The ink-jet recording sheet of claim 1, wherein the void layer contains a hardener.
- 6. The ink-jet recording sheet of claim 5, wherein the hardener, is boric acids or salts thereof.
- 7. The ink-jet recording sheet of claim 1, wherein the support has a specular gloss of 20 to 80 percent.
- 8. The ink-jet recording sheet of claim 2, wherein the support is translucent polyester film, opaque polyolefin resin film or paper laminated with polyethylene on both surfaces of a paper substrate.
- 9. The ink-jet recording sheet of claim 8, wherein the support is paper laminated wish polyethylene on both surfaces of a paper substrate.
- 10. The ink-jet recording sheet of claim 1, wherein the inkjet recording sheet exhibits the specular gloss such that 60 degree specular gloss of an in-recorded part is 3 to 20 percent more than that of a nonink-recorded part.
- 11. The ink-jet recording sheet of claim 10, wherein the inkjet 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. The ink-jet recording sheet of claim 1 comprising the first particles in an amount of 3 to 50 g per 1 m2 of the sheet.
- 13. The ink-jet recording sheet of claim 4 comprising the polyvinyl alcohol in an amount of 0.5 to 10 g per 1 m2 of the sheet.
- 14. The ink-jet recording sheet of claim 1, wherein the second particles are one of titanium oxide, zinc oxide and barium sulfate.
- 15. The ink-jet recording sheet of claim 1, wherein an average particle diameter of the second particles is 0.1 μm to 1.0 μm.
- 16. The ink-jet recording sheet of claim 15, wherein the average particle diameter of the second particles is no more than 0.5 μm.
- 17. The ink-jet recording sheet of claim 1, wherein the second particles is 1 to 20 weight percent with respect to the first particles contained in the void layer comprising the second particles.
- 18. The ink-jet recording sheet of claim 17 wherein
the first particles are present in an amount of 3 to 50 g per 1 m2 of the sheet; and an average particle diameter of the second particles is 0.1 μm to 1.0 μm.
- 19. The ink-jet recording sheet of claim 18, wherein the first particles are silica having an average particle diameter of no more than 100 nm; and the second particles are selected from titanium oxide, zinc oxide and barium sulfate.
