1363779 IX. OBJECTS OF THE INVENTION: TECHNICAL FIELD The present invention relates to a cellulose body composition and a cellulose body film, and more particularly to a denaturing agent for a cellulose body film exhibiting low moisture permeability. A cellulose body composition obtained from the denaturant and a cellulose body film. Further, the present invention relates to a method for producing the cellulose body film. Further, the present invention relates to a polarizing plate protective film, a liquid crystal display device and a silver halide photographic light-sensitive material using the cellulose body film. [Prior Art] The cellulose film has been applied to a photographic carrier or various optical materials due to the strong toughness and flame retardancy of the conventional cellulose film. In particular, in recent years, it has been widely used for optically transparent films for liquid crystal display devices. Since the fluorinated cellulose film has high optical transparency and high optical isotropy, for example, it is excellent as an optical material for processing a polarizing device of a liquid crystal display device, and has been used as a protective film for a polarizer or as an improvement. Use of an optical compensation film carrier for viewing the picture (viewing angle compensation) in an oblique direction. A polarizing film is formed on the polarizing plate of one of the members for a liquid crystal display device at least on one side of the polarizer by bonding. A general polarizer is obtained by dyeing a stretched polyvinyl alcohol (PVA) film using iodine or a dichroic dye. In many cases, a deuterated cellulose film which can be directly bonded to PVA, in particular, a triethylenesulfonyl cellulose film can be used as a protective film for a polarizer. The optical properties of this polarizer protective film greatly affect the characteristics of the polarizing plate. On the other hand, compared with general other transparent carriers, such as poly(p-phenylene) 1363779 diethylene glycol film, the vapor permeability of the cellulose-fluoride film under high temperature and high humidity is significantly increased, due to poor function, Compounds called plasticizers are often added. Conventionally, as a plasticizer added to a deuterated cellulose body, for example, a triglyceride of phosphotitphenyl diphenyl phosphate, a phthalic acid ester or the like (for example, Patent Document η. For example, a sulfonamide compound of N-ethyltoluenesulfonamide is known to increase the moisture permeability and improve the film properties once the amount of such a plasticizer is increased. However, by increasing the amount of the plasticizer, the fiber is deuterated. The glass transition temperature of the plain film will be further lowered, and the dimensional stability will be deteriorated due to the softening of the film. In addition, if the amount of the plasticizer is simply increased, the plasticizer will not be associated with the cellulose-deposited cellulose film. Dissolving, the film becomes cloudy, and the optical anisotropy of the film (for example, the retardation 値Rth in the thickness direction) is increased. When the bismuth cellulose film is used for an optical material, it is preferable to reduce the film depending on the use. Optical anisotropy. It is known that the compound of the so-called plasticizer has an effect of lowering the optical anisotropy of the cellulose-deposited film. For example, specific fatty acid esters have been disclosed (for example, refer to Patent Documents 2 and 3). , 4 and 5) Such a plasticizer has the disadvantage that the moisture permeability is deteriorated under high temperature and high humidity, so that it is eagerly desired that the osmotic cellulose film having low kinetic anisotropy and low moisture permeability under high temperature and high humidity and its denaturation [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei 9-95 5 5 7 [Patent Document 2] Japanese Laid-Open Patent Publication No. Hei 2-1-247717 [Patent Document 3] Japanese Laid-Open Patent Publication No. 2001-336179 [Patent Document 4] Japanese Laid-Open Patent Publication No. 2000-63560 No. 1363779 [Patent Document 5] Japanese Laid-Open Patent Publication No. Hei No. Hei No. Hei.

The deuterated cellulose film used in the present invention is not particularly limited as long as the effect of the present invention can be found, and two or more different deuterated cellulose bodies may be used in combination. Among them, the following compounds can be mentioned as preferred deuterated cellulose bodies. Namely, the degree of substitution of the cellulose body with respect to the hydroxyl group of the cellulose is a cellulose obtained by satisfying all of the following formulas (I) to (III). (I) 2.6 <SA + SB <3.0 (II) 1. 8 <S A <3.0 (III ) 0 <SB <0. 8 of which. In the formula, SA+SB represents the degree of substitution of a thiol group substituted with a hydroxyl group of cellulose, and S A is a degree of substitution of an ethane group, and a degree of substitution of a thio group of SB-based carbon atoms of 3 to 22. The β-l,4-sugar oxygen bond constitutes a sugar unit of cellulose having a free hydroxyl group at the 2-, 3- and 6-positions. A polymer (polymer) in which some or all of the hydroxyl groups are esterified. In the present specification, the term "thiol substitution" means the ratio of cellulose esterification at each of positions 2-, 3- and 6-, and the so-called all-thiol substitution degree indicates the total of these ratios. Specifically, when 100% of each of the hydroxyl groups of 2-, 3- and 6- of the cellulose is esterified, the degree of substitution is set to -32·1363779 1. Thus, when all 100% of all 2-, 3- and 6- are esterified, all thiol substitutions will become the largest 3. The sum of the degrees of substitution of SA and SB of the hydroxyl group of the present invention is preferably 2. 7~2. 96, especially 2. 80~2. 95 is more ideal. In addition, the degree of substitution of SB is preferably 0~0. 8, especially 0~0. 60 is more ideal. Further, 28% or more of SB is preferably a 6-hydroxyl substituent, more preferably 30% or more is a 6-hydroxyl substituent, and is preferably 31% or more, particularly 3.

'-33- 1363779 The basic principle of the method for synthesizing deuterated cellulose has been disclosed in the "Wood Chemistry", Koda, et al., pp. 18-190 (Kyoritsu Publishing, 1968). A representative synthesis method utilizes a liquid phase deuteration method using a carboxylic anhydride-acetic acid-sulfuric acid catalyst. Specifically, 'pre-treatment of the cellulose raw material such as cotton linters or pulp with an appropriate amount of acetic acid, and then pouring the pre-cooled carboxylated mixture to carry out esterification 'synthesis of fully deuterated cellulose bodies (2-, The thiol substitution at the 3- and 6-positions is approximately 3. 00). The carboxylated mixture contains acetic acid as a solvent, anhydrous carboxylic acid as an esterifying agent, and sulfuric acid as a catalyst. The amount of water-free carboxylic acid used is stoichiometrically higher than the total amount of cellulose that reacts with it and the amount of water present in the system. After the completion of the deuteration reaction, a neutralizing agent (for example, calcium, magnesium, iron, aluminum or zinc carbonate) is added in order to carry out the hydrolysis of the excess anhydrous carboxylic acid remaining in the system and the neutralization of a part of the esterification catalyst. An aqueous solution of a salt, acetate or oxide. Next, the obtained fully deuterated cellulose body is completely saponified by maintaining a temperature of 50 to 90 ° C in the presence of a small amount of a deuteration reaction catalyst (usually residual sulfuric acid), and is changed to have a desired mercapto group. The degree of substitution and the degree of polymerization of the deuterated cellulose body. When the desired cellulose material is obtained, the neutralizing agent is used to completely neutralize the catalyst remaining in the system, or the neutralization of the cellulose solution is poured into water or diluted. Among the sulfuric acid (or water or dilute sulfuric acid is poured into the deuterated cellulose body solution), the deuterated cellulose body is separated, and the deuterated cellulose body is obtained by washing and stabilization treatment. The polymer component of the constituent film of the cellulose-degraded cellulose film of the present invention is preferably a cellulose-deposited body having the definition. The term "actually" means 55 mass% or more of the polymer component (preferably 70 to 100% by mass, more preferably -34 to 1363779, more preferably 80 to 100% by mass, still more preferably 90 to 100% by mass). As a raw material for the production of a film, it is preferred to use a deuterated cellulose body particle. More than 90% by mass of the particles used, preferably having a ruthenium. Particle size of 5~5mm. Further, 50% by mass or more of the particles to be used preferably have a particle diameter of 1 to 4 mm.

The preferred degree of polymerization of the cellulose-defected cellulose used in the present invention has a viscosity average polymerization degree of 200 to 700, preferably 250 to 550, more preferably 250 to 400, and an average degree of polymerization of 250 to 350. ideal. The average degree of polymerization can be measured by the limit viscosity method of Uda et al. (Uda Kazuo, Saito Hideo, Fiber Society, Vol. 18, No. 1, pp. 105-120, 1962). Further, it has been disclosed in Japanese Laid-Open Patent Publication No. Hei 9-95538. When the low molecular component is removed, although the average molecular weight (degree of polymerization) becomes high, it is useful because the viscosity is lower than that of the general deuterated cellulose body. The deuterated cellulose body having a small amount of low molecular components can be obtained by removing a low molecular component from the synthesized deuterated cellulose body by a general method. The removal of the low molecular component ' can be carried out by washing the deuterated cellulose body with a suitable organic solvent. Further, in the case of producing a deuterated cellulose body having a low molecular component, it is preferable to adjust the amount of the sulfuric acid catalyst for the deuteration reaction to 0% with respect to 100 parts by mass of the cellulose. 5 to 25 parts by mass. When the amount of the sulfuric acid catalyst is set within this range, it is also possible to synthesize a preferred (molecular weight distribution uniform) cellulose-based cellulose body based on the molecular weight distribution.

'And a cellulose film with low moisture permeability. In the case of TPP, the related optical anisotropy can be greatly reduced by adding the denaturant of the present invention. According to the estimation by the inventors of the present invention, for example, according to the B-7, CN1, D-2, and E-1 of the present invention, a compound in which three or more rings are bonded to one atom is directly formed by the ring structure. Since the steric obstacle is difficult to align in the same direction, the optical anisotropy can be reduced. However, even if there are more than three rings, the ring is not directly bonded to one atom, and the compound such as TPP does not reduce optical anisotropy but increases optical anisotropy by comparing samples 1 and 2. The comparison can be clearly known. &lt;Example 2&gt; Using the same method as in Example 1, a cellulose-deposited film was produced using the following composition. Cellulose triacetate (degree of deuteration 60.9%) (1 part by mass) dichloromethane (3 parts by mass) methanol (45 parts by mass) The denaturant used in the samples 2 to 10 disclosed in Example 1 ( 11.7 parts by mass) In the same manner as in Example 1, the cellulose body film of the present invention can also give good results. &lt;Example 3&gt; Polarizing plate protective film - 60 - 1363779 With respect to the sample 2 to 1 3 of the first embodiment, the sample 3 was produced and evaluated by the method disclosed in Example 1 of Japanese Laid-Open Patent Publication No. Hei 11-316378. Polarized plate protective film of 02 ~ 313. The optical properties of the elliptically polarizing plate protective film obtained by using the woven voxel film of the present invention are extremely excellent. Further, there is no particular problem with the durability over time as compared with the protective film obtained from Comparative Sample 2. &lt;Example 4&gt; Liquid crystal display device The liquid crystal display device of Example 1 disclosed in Japanese Laid-Open Patent Publication No. Hei 10-48420 was produced and evaluated in each of the samples 2 to 13 of the first embodiment; An optically anisotropic layer containing discotic liquid crystal molecules and a nematic film coated with polyvinyl alcohol in Example i of Japanese Patent Publication No. 9-26572, which is disclosed in Japanese Laid-Open Patent Publication No. 2000-155466-1 A VA type liquid crystal display device of Figs. 2 to 9 is a 〇CB type liquid crystal display device disclosed in Figs. 1 to 15 of Japanese Laid-Open Patent Publication No. 2000-154261. The apparatus obtained by using the cellulose body membrane of the present invention can obtain good performance in either case. &lt;Example 5&gt; Silver halide photo-sensitive material Samples 502 to 513 were prepared in the same manner as in Example 1 except that the film thickness of Example 1 to Example 13 of Example 1 was changed to 12 Å. On the side surface of the obtained film, the first layer and the second layer of Example 1 disclosed in Japanese Laid-Open Patent Publication No. Hei. Further, the opposite layer of the film substrate to which the obtained back surface layer is applied is coated with the same composition as that of the sample ι〇5 of Example 1 disclosed in Japanese Laid-Open Patent Publication No. Hei No. Hei. A silver halide photographic material is used. The silver halide obtained by using the cellulose body-61 - 1363779 film of the present invention has no problem in terms of operability.
