A peeling force controller is added to a dope to be cast on a support. The peeling force controller is polycarboxylic derivatives, in which a content of said polycarboxylic acid is at most 50 wt. %. During peeling the cast dope as a film from the support, the peeling force is at most 60×9.8 (mN) per 1 cm in width of the film. Thus the film is peeled stably and speedy from the support, and the generation of metal salts of the peeling force controller is reduced such that the pollution of a film production apparatus is prevented. Accordingly, the film excellent in optical property is continuously produced at high speed.

Data that is to be written is received, wherein the data is indicated in one or more blocks of a first block size. Each of the one or more blocks of the first block size is written in consecutive blocks of a second block size that is larger in size than the first block size, wherein each of the consecutive blocks of the second block size stores only one block of the first block size, and wherein each of the consecutive blocks of the second block size has empty space remaining, subsequent to the writing of each of the one or more blocks of the first block size. Filler data is written in the empty space remaining in each of the consecutive blocks of the second block size.

摘要:
A cellulose acetate solution is filtrated with a filter medium formed of cellulose fiber. Hydroxyl groups on the filter medium are substituted to other functional groups. An acidic material is added to the cellulose acetate solution, and the filtration is preformed. In order to estimate the hydrogen ion concentration of the organic solvent, a sample solvent of thereof is mixed with water so as to transport hydrogen ions from the sample solvent to the water of a predetermined volume. Then the water is separated from the sample solvent, and the pH value of the water is measured with a pH meter. The result of the measurement is regarded as the pH value of the organic solvent.

A solvent in which dichloromethane is mixed with alcohol as a poor solvent is used for preparing a dope. Alcohol is supplied to the dope in a inline pipe to mix with a static mixer, such as a casting dope in which a composition of alcohol is increased. The temperature of the rotary drum is adjusted to −7° C. The casting dope is fed from a casting die to the rotary drum so as to form a casting film whose thickness is 40 μm. Since the content of alcohol is high and a storage modulus of the cooled casting film is at least 150 thousands Pa, the peeling defect does not occur, and the stretch is reduced as far as possible. A gel-like film is dried by a tenter type drying device, and stretched such that the stretch ratio is at most 110%. The produced film is thin and excellent in a surface condition and optical isotropy.

摘要:
A toner resin composition comprising a linear polyester resin (A) containing a C3 to C10 aliphatic diol component and a linear polyester resin (B) containing a C3 to C10 aliphatic diol component which differs from the linear polyester resin (A), or further comprising a vinyl-based resin (C), and a toner containing the toner resin composition as a binding resin. A toner excellent in low temperature fixability, offset resistance, gloss, etc. and excellent in range of fixing temperature can be obtained.
摘要:
In a multi-layer structure of a cellulose acylate film, the averaged degree of acylation of surface layers is controlled in the range of 0.5 to 2.8 by mixing several sorts of cellulose acylates having different averaged degrees of acyation. One of the surface layers is formed on a substrate by casting a solution containing cellulose acylate made of cotton linter. Lubricant particles are added to a solution for the surface layers, and emission compounds to a solution for the inner layers. The obtained cellulose acylate film is excellent in adhesive property to the hydrophobic material without saponification, and adequately used for the polarizing filter, an optical compensation sheet, and liquid crystal display.
