An excellent anti-reflection circular polarizer for preventing the reflection of external light is provided, and thereby an excellent image display device with very little degradation of anti-reflection functionality caused by decreased levels of polarization under conditions of high humidity while having little deformation of an image display panel is provided. In particular, an anti-reflection circular polarizer suitable for an organic EL image display device is provided. The anti-reflection circular polarizer includes a reflection reduction layer, a light-transmissive substrate film, a polarizing element, and a λ/4 phase-difference layer, stacked in this order, wherein the light-transmissive substrate film has a moisture permeability of 100 g/m·day or less.

Provided is a hydrolysis-resistant polyester film having a low acid value due to suppression of acid value-increase during film formation. The hydrolysis-resistant polyester film of the present invention is a polyester film comprising a polyester resin composition, wherein the polyester resin composition that forms the films comprises 0.03 to 6.7 eq/ton of hindered phenol structural units, an acid value of a polyester that forms the film is less than 25 eq/ton, and an intrinsic viscosity of a polyester that forms the film is more than 0.64 dL/g and not less than 0.90 dL/g.

Hydrolysis-resistant polyester film

The present invention is directed to a heat-resistant polyester blow-molded article made of a polyester resin composition containing 0.035 to 1.75 equivalent/ton of a hindered phenol structural unit and containing at least one selected from the group consisting of antimony compounds as a polymerization catalyst, the cyclic trimer content thereof being less than or equal to 0.5% by mass, the acetaldehyde content thereof being less than or equal to 50 ppm and the intrinsic viscosity thereof being 0.68 to 0.90 dL/g. The present invention enables efficient production of a molded article excellent in transparency and heat-resistant dimensional stability, in particular a heat-resistant blow-molded article. Moreover, according to the present invention, there are provided a polyester resin composition which is excellent in long-term continuous moldability and hardly stains a mold and a molded article prepared therewith, and a method for molding a polyester blow-molded article using the polyester resin composition.

A label having a thermoplastic polymer film and an ink layer formed on at least one surface thereof, the ink layer being removable in alkaline hot water, can easily be recycled after separated or without being separated from the bottle into polymer pellets with improved purity. The recycled polymer pellets are extremely suitable for the effective use of resources because they contain substantially no ink and can therefore find various applications.

There is disclosed a system for developing photosensitive resin plates with an aqueous developing solution and for disposing of a waste developing solution. In the system, a fresh developing solution is added to a developing unit in a continuous manner or at intervals of a fixed period, while a part of the resin-containing developing solution is removed from the developing unit, whereby the resin content of the developing solution in the developing unit is kept substantially constant and the disposal of the waste developing solution is carried out in parallel with the development. Also disclosed herein are apparatus used in the developing system.
