A process for the preparation of polyethylene terephthalate by making use of non antimony catalysts is described. The Ti complex catalyst is pre-dispersed in the polymer matrix selected from PET, PBT, PCTG, PETG, PCT, PEN, PPT, PTT or any other related polyesters and prepared as a master batch. The key feature of the process is that the polyester obtained is having good whiteness, as against the yellowness normally encountered with Ti based catalysts, and also the polyester has very good clarity with minimum haze.

An aqueous ink comprising water, a water-soluble organic solvent and at least two pigments. The aqueous ink is used together with a reaction liquid containing a reactive component that reacts with the aqueous ink to cause aggregation or gelation of the aqueous ink. The at least two pigments have a difference in precipitation value to the reaction liquid of 0.2 or less.

The object of the present invention is to provide an oxygen-absorbing resin composition having a high oxygen absorbability and capable of absorbing oxygen for a long period of time. The present invention provides an oxygen-absorbing resin composition comprising polyolefin resin (A) obtained by polymerizing an olefin having 2 to 8 carbon atoms, resin (B) which is other than resin (A) and which acts as a trigger for the oxidation of resin (A), and transition metal catalyst (C), wherein resin (B) is dispersed in the matrix of resin (A) so that the oxidation reaction of matrix resin (A) is caused and thus oxygen is absorbed when the oxygen-absorbing resin composition is brought into contact with oxygen. This oxygen absorbing resin composition has a high oxygen absorbability and is advantageous in cost because oxygen is absorbed in resin (A).

There is provided a material which is free from fading into white due to surface scattering and is useful as a laminated article having excellent adhesion and practical low reflection. A fluorine-containing compound which has a hydrolyzable metal alkoxide moiety and is represented by the formula (1):wherein X1 and X2 are the same or different, and each is H or F; X3 is H, F, CH3 or CF3; X4 and X5 are the same or different, and each is H, F or CF3; Rf1 is a fluorine-containing alkyl group having 1 to 40 carbon atoms or a fluorine-containing alkyl group having 2 to 100 carbon atoms and ether bond, which is an organic group in which 1 to 3 hydrogen atoms are replaced by Y1 where Y1 is a functional group having, at its end, at least one hydrolyzable metal alkoxide moiety having 1 to 10 carbon atoms; a is 0 or an integer of 1 to 3; b and c are the same or different, and each is 0 or 1, a curable fluorine-containing polymer obtained from the above-mentioned compound, and a curable fluorine-containing resin composition comprising the polymer.

A skin care and shaving system is provided comprising disposable razor cartridge with one or more blades, skin engaging applicator member made of sponge like material and a handle for holding. The sponge like material includes small and large pore sponge and also foam pad which helps in applying all kinds of skin shaving enhancer such as shaving cream, lotion, gel, moisturizer during pre and post shave. Further, in another aspect of the present invention, it is provided a skin enhancer cartridge comprising a handle and a skin engaging applicator member without and razor blades attached to the system. The product of the present invention is a disposable one wherein the whole shaving system is disposable or in some cases the handle of the cartridge can be reused.

An image detector has an I / V converter for converting, into a voltage output., a current output as a result of a photoelectric element arranged in a traveling direction of an intermediate transfer belt having received light reflected from the intermediate transfer belt and light reflected from toner images formed on the intermediate transfer belt; a peak-hold unit for holding an output voltage into which the light reflected from the intermediate transfer belt has been converted by the I / V converter; and a computation unit for detecting a difference between the output voltage of the peak-hold unit and an output voltage into which the light reflected from the toner images of respective colors has been converted by the I / V converter.

The present invention provides a liquid crystal panel that can provide a neutral display that is free from coloring in every direction. The liquid crystal panel includes a first polarizer 14a, a second polarizer 14b, and a liquid crystal cell 13. The first polarizer 14a is arranged on the visible side of the liquid crystal cell 13 and the second polarizer 14b is arranged on the backlight side of the liquid crystal cell 13. The liquid crystal panel further includes a first retardation layer 11 and a second retardation layer 12. A refractive index ellipsoid of the first retardation layer 11 has a relationship of nx=ny>nz, and a refractive index ellipsoid of the second retardation layer 12 has a relationship of nx>ny≧nz. The first retardation layer 11 and the second retardation layer 12 are arranged between the liquid crystal cell 13 and the second polarizer 14b.

Ethylene-vinyl alcohol copolymer pellets comprise an ethylene-vinyl alcohol copolymer and water, and have a water content of not higher than 0.5 wt. %, wherein the ratio (Y / Z) of a lactone ring content (Y) to the sum (Z) of a carboxylic acid content (X) and the lactone ring content (Y) in terminal structures of the ethylene-vinyl alcohol copolymer is not less than 60 mol %. The pellets are excellent in high-temperature thermal decomposition-suppressing effect and thermal stability, and are free from odor emanation and coloration even if being processed at a higher temperature.

The present invention provides a liquid crystal display device having a high contrast ratio and no coloring during black display, over a wide viewing angle range. The liquid crystal display device of the present invention includes a reverse wavelength dispersion-type biaxial retardation film having R0(B) / R0(G) and Rth(B) / Rth(G) not greater than 0.965 and R0(R) / R0(G) and Rth(R) / Rth(G) not smaller than 1.015; and a vertical alignment liquid crystal cell that has a blue, a green, and a red color filter layer and that satisfies Rth_LC(B) / Rth_LC(G)≦1.000 and Rth_LC(R) / Rth_LC(G)≧1.000. R0(B), R0(G) and R0(R) denote the in-plane retardations of the retardation film at wavelengths 450 nm, 550 nm and 650 nm. Rth(B), Rth(G) and Rth(R), and Rth_LC(B), Rth_LC(G) and Rth_LC(R) respectively denote the thickness-direction retardations of the retardation film and the liquid crystal cell at wavelengths 450 nm, 550 nm and 650 nm.
