Claims
- 1. A photographic support consisting essentially of a substrate and a resin layer provided at least on the side of the substrate where images are to be formed, said resin layer comprising (A) a polyolefin resin or a polyolefin resin mixture, (B) a titanium dioxide pigment, (C) a fluorescent agent and (D) at least one member selected from the group consisting of a color pigment and a color dye, said titanium dioxide pigment having a number-average diameter of 0.110-0.150 .mu.m and having been subjected to at least one treatment selected from the group consisting of (1) a surface treatment with aluminum-containing hydrated metal oxides to coat the titanium dioxide pigment with (a) an aluminum-containing metal composition in an amount of more than 0.2% by weight, but less than 1.8% by weight in terms of anhydrous metal oxide based on the weight of the titanium dioxide pigment and (b) a silicon composition in an amount of 0 inclusive-0.4 inclusive % by weight in terms of anhydrous silicon dioxide based on the weight of the titanium dioxide pigment and (2) an inside treatment with an aluminum compound to contain, in the titanium dioxide pigment, an aluminum composition in an amount of more than 0.2% by weight, but less than 1.8% by weight in terms of anhydrous aluminum oxide based on the weight of the titanium dioxide pigment, and said fluorescent agent being a bis(benzoxazolyl) naphthalene type fluorescent agent having a substituent or a bis(benzoxazolyl)stilbene type fluorescent agent having a substituent.
- 2. A photographic support according to claim 1, wherein the color pigment and color dye are a combination of a blue pigment and a magenta pigment and a combination of a blue dye and a magenta dye, respectively.
- 3. A photographic support according to claim 1, wherein a combination of a blue pigment and a magenta dye; or a combination of a magenta pigment and a blue dye is contained.
- 4. A photographic support according to claim 1, wherein the fluorescent agent is contained in a proportion of 0.3-30 mg/m.sup.2.
- 5. A photographic support according to claim 1, wherein the titanium dioxide pigment has a rutile structure.
- 6. A photographic support according to claim 1, wherein the titanium dioxide pigment is contained in an amount of 9-30% by weight based on the weight of the resin layer.
- 7. A photographic support according to claim 1, wherein the polyolefin resin is a polyethylene type resin.
- 8. A photographic support according to claim 1, wherein the polyolefin resin mixture comprises two or more polyethylene type resins.
- 9. A photographic support according to claim 1, wherein the resin layer additionally contains a metal salt of a higher fatty acid.
- 10. A photographic support according to claim 1, wherein the resin layer additionally contains an antioxidant.
- 11. A photographic support according to claim 10, wherein the antioxidant is a hindered phenol type antioxidant.
- 12. A photographic support according to claim 1, wherein the titanium dioxide pigment has been ground in a fluid energy mill.
- 13. A photographic support according to claim 12, wherein the fluid energy mill is a steam mill.
