wherein thermoplastic resin particles, porous particles and a cationic material selected from the group consisting of polymer mordants, trimethyl-type cationic materials, dialkyl-type cationic materials, benzyl-type cationic materials, amine salt-type cationic materials and imidazoline-type cationic materials are contained in any one of said back layers.
2. The image receiving material as claimed in claim 1 , wherein said porous particles are inorganic particles and/or polymer particles.
3. The image receiving material as claimed in claim 1 , which has a back layer containing the porous particles and the thermoplastic resin together.
4. The image receiving material as claimed in claim 1 , wherein the content of said porous particles in the back layer is within a range from 1 g/m 2 to 30 g/m 2 .
5. The image receiving material as claimed in claim 4 , wherein the content of said porous particles in the back layer is within a range from 5 g/m 2 to 20 g/m 2 .
6. The image receiving material as claimed in claim 1 , wherein said porous particles have an average particle size of 300 nm or below.
7. The image receiving material as claimed in claim 6 , wherein said porous particles have an average particle size of 100 nm or below.
8. The image receiving material as claimed in claim 1 , wherein said porous particles are silica particles and/or alumina particles.
9. The image receiving material as claimed in claim 2 , wherein said polymer particles have an average particle size of 500 nm or below.
10. The image receiving material as claimed in claim 2 , wherein said polymer particles are self-crosslinking polymer particles having cationic groups.
11. The image receiving material as claimed in claim 1 , wherein said cationic material is a cationic resin.
12. The image receiving material as claimed in claim 1 , wherein the content of said cationic material in the back layer is within a range from 0.1 g/m 2 to 15 g/m 2 .
13. The image receiving material as claimed in claim 12 , wherein the content of said cationic material in the back layer is within a range from 0.5 g/m 2 to 8 g/m 2 .
14. The image receiving material as claimed in claim 1 , wherein said cationic material is a polymer mordant.
15. The image receiving material as claimed in claim 14 , wherein said polymer mordant is selected from the group consisting of a mordant polymer containing tertiary amino group, a mordant polymer having nitrogen-containing heterocyclic portion, and a mordant polymer containing quaternary cationic group.
16. The image receiving material as claimed in claim 1 , wherein said back layers are formed using a water-soluble polymer and/or latex dispersion.
17. The image receiving material as claimed in claim 1 , wherein said back layer contains a binder in an amount of 100 wt % or less of total particles contained therein.
18. The image receiving material as claimed in claim 17 , wherein said back layer contains a binder in an amount of 30 wt % or less of total particles contained therein.
19. The image receiving material as claimed in claim 1 , wherein said back layer contains a film hardening agent for the binder.
20. The image receiving material as claimed in claim 1 , wherein said back layer contains a matting agent, a slipping aid and/or a charge controlling agent.
21. An image receiving material for electronic photograph comprising:
a support made of base paper having a polyolefin resin layer on each side of the support;
a toner receiving layer, provided on one side of said support, which contains a thermoplastic resin; and
one or more back layers provided on the other side of said support,
wherein thermoplastic resin particles, porous particles and a cationic material are contained in any one of said back layers, and wherein the content of said porous particles in the back layer is within a range from 5 g/m 2 to 20 g/m 2 .
