Nos. 5 and 6 may be striped magnetic layers, but transparent magnetic layers are preferred.

When the magnetic layer is a transparent layer, the optical density is preferably 1.0 or less, more preferably 0.75 or less, and particularly preferably 0.02 to 0.30.

In the present invention, the transparent magnetic recording layer is a layer in which ferromagnetic powder is dispersed in a binder.

Examples include hexagonal Ba ferrite, Sr ferrite, lead ferrite, Ca ferrite, or solid solutions or ion-substituted products of these types.

In the hexagonal ferrite magnetic powder, a part of Fe atoms, which are the constituent elements of these uniaxially anisotropic hexagonal ferrite crystals, are mixed with a divalent metal, Nb, Sb ₄ and Ta.
At least one pentavalent metal selected from the above and an element having a coercive force of 200 to 2,000 Oe substituted by Sn atoms in the range of 0.05 to 0.5 per chemical formula are used.
The divalent metal in hexagonal ferrite is Mn, C
Elements such as u and Mg that relatively well replace Fe atoms in ferrite are preferred. In hexagonal ferrite, the proper substitution amount of divalent metal (MII) and pentavalent metal (Mv) is MI.
Although it depends on the combination of I and Mv, it is preferably about 0.5 to 1.2 per chemical formula of MII.

Looking at the relationship of the substitution amount of the substitution element, for example, for magnetoplumbite type Ba ferrite, the chemical formula of the substitution body is BaFe _{12- (x + y + z)} MII _x Mv _y Sn _z O.
It is represented by ₁₉ . Here, x, y and z are substitution amounts of MII, Mv and Sn elements per one chemical formula of ferrite. MII, M
v and Sn are divalent, pentavalent, and tetravalent, respectively, and the Fe atom to be substituted is trivalent, so that the relation of y = (x−z) / 2 is obtained in consideration of price number compensation. That is, the substitution amount of Mv is uniquely determined from the substitution amount of MII and the substitution amount of Sn.

The coercive force (Hc) of the ferromagnetic powder is usually 2
It is at least 00 oersted, preferably at least 300 oersted. The size of the magnetic powder in the major axis direction is preferably 0.3 μm or less, more preferably 0.2 μm or less. The specific surface area of the ferromagnetic powder by the BET method is usually 20 m ² / g
The above is preferably 25 to 80 m ² / g. The shape of the ferromagnetic powder is not particularly limited, and for example, any shape such as a needle shape, a spherical shape, or an ellipsoidal shape can be used.

Fatty acids can be contained in the magnetic recording layer of the present invention. The fatty acid may be monobasic or dibasic, and the preferred fatty acid in the present invention has 6 to 30, particularly 12 to 22 carbon atoms, and is particularly preferred. Myristic acid, oleic acid, and stearic acid.

When the fatty acid ester is contained in the magnetic recording layer, the friction coefficient of the magnetic layer is lowered and the running property and durability of the magnetic recording medium of the present invention are further improved. Preferred fatty acid esters are butyl stearate and butyl palmitate. The fatty acid ester may be used alone or in combination of two or more.

The magnetic layer of the present invention may contain another lubricant in addition to the fatty acid and / or fatty acid ester.

Examples of other lubricants include silicone-based lubricants, fatty acid-modified silicone-based lubricants, fluorine-based lubricants, liquid paraffin, squalane, and carbon black. These may be used alone or in combination of two or more.

As the binder, a transparent one such as cellulose ester or gelatin is used.

A dispersion of finely divided magnetic particles in a transparent binder such as cellulose ester or gelatin using an organic solvent for cellulose ester or a solvent for the binder such as water for gelatin. Can be prepared.

As an organic solvent used for dispersing, kneading and coating the magnetic particles, an acetone-based solvent such as acetone, methyl ethyl ketone and cyclohexanone; an alcohol-based solvent such as propanol, butanol and isobutyl alcohol; Butyl, isopropyl acetate, etc. ester type; glycol dimethyl ether, etc. ether type; xylene, etc. tar type (aromatic hydrocarbon);
Chlorinated hydrocarbons such as methylene chloride and ethylene chloride can be used.

Prior to coating, the support may be subjected to corona discharge treatment, plasma treatment, undercoating treatment, heat treatment, dust removal treatment, metal vapor deposition treatment, and alkali treatment. Regarding these supports, for example, West German Patent 3,338,854A
No. 59-116926, U.S. Pat. No. 4,38
No. 8,368, Yukio Mitsuishi, "Fiber and Industry", Volume 31,
p50-55, 1975 and the like.

In the present invention, the transparent magnetic recording layer may be formed by incorporating magnetic particles into the support.

In that case, it is preferable to concentrate on the side of the support opposite to the side on which the photographic constituent layers are coated. As a method of concentrating on one surface side of the support, after casting a dope containing a support polymer and magnetic particles, the magnetic particles are concentrated on one surface side of the support by gravity, magnetic force, etc. Kosho 30-986, WO91 / 11
As shown in 750, there is a method in which the dope containing the magnetic particles and the dope not containing the magnetic particles are simultaneously cast and concentrated on one surface side of the support, but the latter is preferable because it can be manufactured at a high speed. .

In the present invention, the triacetate cellulose ester dope containing magnetic particles and the cellulose triacetate ester dope not containing magnetic particles can be simultaneously cast on a drum or belt and dried to form a support. There are two casting openings on the top,
It is also possible to cast the cellulose triacetate ester dope first, and then cast the cellulose acetate triacetate dope containing magnetic particles thereon and dry it to form the support of the present invention.

The thickness of the support is preferably 50 to 150 μm.
m, more preferably 60 to 130 μm, particularly preferably 70 to 120 μm. If the thickness is less than this, the accuracy of writing and reading by the magnetic head is reduced with respect to the high-speed coating speed of the silver halide photosensitive material, which is not preferable. On the other hand, if it is thicker than this, the suitability for exposure / developing equipment as a silver halide photosensitive material is deteriorated.

In the support which can be used in the present invention, the thickness of the layer in which the magnetic particles are present is 2 μm or less, preferably 1.5.
It is not more than μm, particularly preferably not more than 1 μm and not less than 0.1 μm. The coating amount of the magnetic particles is 10 to 1000 mg / m ² ,
Preferably 15 to 300 mg / m ² , particularly preferably 2
It is 0 to 100 mg / m ² .

The magnetic particles are mainly composed of iron oxide, but those having a small amount of aluminum, calcium and silicon doped therein are preferably used for the purpose of the present invention. The acicular ratio of the magnetic particles is preferably 1-7.

In the process of casting the dope containing the magnetic particles and drying the dope to form the magnetic recording layer, the magnetic particles may be regularly oriented by facing magnets, or a random magnetic field may be applied to the magnetic particles. Randomizing treatment is also effective in the present invention.

As the polymer forming the support, cellulose triacetate is preferable, but polyethylene terephthalate may be used. In this case, it is preferable to use the so-called coextrusion method in the production of the support. Further, in the case of polyethylene terephthalate, JP-A-1-244446, 1-291248 and 1-2
98350, 289045, 2-93641
It is preferable to use polyethylene terephthalate having a high water content as disclosed in No. 2, No. 2-181,49, No. 2-214852, and Japanese Patent Application No. 2-291135, because the dispersion stability of magnetic particles is improved.

It is preferable to add a small amount of a known dye or pigment to the support to prevent halation, irradiation and light piping.

By adding an inorganic or organic matting agent to the dope containing the magnetic particles, or by matting the surface after forming the magnetic layer, the surface roughness is set to a certain region. The efficiency of writing and reading by the head can be improved.

By adjusting the viscosity balance, changing the solvent composition, adjusting the surface tension, and changing the plasticizer content of the dope containing magnetic particles and the dope not containing magnetic particles, Physical properties can be adjusted.

After forming the support, the process can be simplified by applying an undercoat layer or a backing layer online.

In the present invention, the surface protrusions of the magnetic recording layer can be formed by adding fine particles to the magnetic recording layer or by modifying the surface state of the coating film by utilizing the reticulation or the Marangoni effect. It is preferable to add fine particles for stable reproduction in production.

As the fine particles to be added to the magnetic recording layer, the inorganic and organic matting agents described below, which are usually used in the surface protective layer of a silver halide color light-sensitive material, can be used.
The particle size is preferably 0.1 to 2 μm, and the addition amount is 1
To 100 mg / m ² is preferred.

The average height of the surface protrusions of the magnetic recording layer is
The thickness is 0.1 μm or more and 0.5 μm or less, which depends on the thickness of the magnetic recording layer, the fine particles added, and the shape and particle size of the magnetic material.

In the present invention, when the surface friction coefficient of the magnetic recording layer is 0.10 or more and 0.25 or less, the effect of the present invention is further enhanced.

Next, the outermost surface containing the matting agent in the photographic constituent layers of the light-sensitive material of the present invention will be described.

In the present invention, the matting agent is water-insoluble or sparingly water-soluble inorganic or organic particles. Examples of the inorganic particles include silica, colloidal silica, titanium oxide, glass powder and barium sulfate. Examples of the organic particles include synthetic polymers such as polystyrene, polymethylmethacrylate, polycarbonate, and polyacrylate copolymer, and natural products such as starch and corn starch. In particular, the acrylic ester-acrylic acid copolymer is useful because it can be completely removed, partially removed, or left in the development processing step by adjusting the molar ratio thereof. In the present invention, those which remain at least partially after the development treatment are preferred.

In the present invention, the monodispersity of the matting agent particles means the sphere equivalent diameter (ΣNV ² /

And R ₅ are each a substituted or unsubstituted alkyl group (methyl group, ethyl group, 2-methoxyethyl group, 2-hydroxyethyl group, i-propyl group, n-butyl group, t
-Butyl group, 2-ethylhexyl group, etc.), a substituted or unsubstituted aryl group (phenyl group, p-tolyl group, p
-Methoxyphenyl group, naphthyl group, etc.) or a substituted or unsubstituted heterocyclic group (imidazolyl group, pyrazolyl group, triazolyl group, tetrazolyl group, pyridyl group, thiazolyl group, oxazolyl group, etc.). M represents a hydrogen atom or a cation (sodium, potassium, ammonium group, etc.). x, y and z each represent a molar ratio of an ethylenically unsaturated compound, and z / (x + y) <0.30, preferably z / (x + y) <0.20, and more preferably 0.05 <z. /(X+y)<0.12. z /
When the value of (x + y) is 0.05 or less, aggregation of the matting agent is likely to occur, which is not preferable, and when it is 0.30 or more, the residual amount after the development processing is too small and the physical properties after the development processing are deteriorated.

In the present invention, any known method may be used to adjust the monodispersity of the matting agent particles. For example, the method for dispersing photographic additives described in JP-A-5-296045 can be used. Further, so-called classification as disclosed in JP-A-5-289225 may be carried out, but it requires a complicated operation in production,

There are a two-step swelling polymerization method in which a swelling aid is applied to the seed, and a dynamic swelling polymerization method in which a monomer is precipitated in the seed. Further, in the present invention,
The nozzle ejection method is effective. That is, it is a method in which a solution of a polymer dissolved in a low boiling point organic solvent (ethyl acetate, butanol, etc.) is jetted into agitated water at a constant speed from a fine nozzle whose diameter is controlled. Furthermore, water temperature, stirring conditions, protective colloid agents and surfactants in water,
The addition of salts, the temperature and concentration of the polymer solution, the jetting speed, etc. can be adjusted appropriately. By this method, not only the average particle size but also the monodispersity can be effectively adjusted. Further, as commercially available products, acrylic powder (MX-150, 300, 50 by Soken Chemical Industry Co., Ltd.) is used.
0,1000,1500) can also be used.

g or less, preferably 3 mg or more and 20 mg or less. 1
If it is less than mg, the effect of the present invention is not exhibited, and if it is more than 30 mg, the physical properties of the coating film are significantly impaired.

JP-A-5-289225 describes a monodisperse matting agent as a silver halide color light-sensitive material for movies. This is an invention intended to prevent the generation of Newton's rings and the deterioration of graininess in contact printing, and the outermost surface of the photographic constituent layer side of the silver halide color light-sensitive material having such a magnetic recording layer and the outermost surface thereof. The present invention is different in purpose and application from the present invention intended to prevent scratches due to interaction with the magnetic recording layer located on the opposite side of the support and to improve the accuracy of reading magnetic information.
