摘要:
The invention relates to an optical film containing aromatic polymer which shows high solubility to solvents, and methods for production thereof. Further, the invention also relates to an optical laminate, a polarizing plate, and an image display device each using the optical film. The optical film may be attained by using polyester with a specific structure. The polyester with a specific structure may be obtained by condensation polymerization of bisphenol compound(s) and dicarboxylic acid compound(s) with biphenyl structure, and preferably has no halogen atom in its chemical structure. The optical film of the invention advantageously has not only high solubility in solvents but also a high level of heat resistance and birefringence producing capability. When the content of the biphenyl structure is high, the optical film of the invention can also have large wavelength dispersion of birefringence.

摘要:
The invention relates to a resin solution containing polyester with a specific structure, an optical film containing said polyester, and methods for production thereof. Further, the invention also relates to an optical laminate, a polarizing plate, and an image display device each using the optical film. The polyester may be obtained by condensation polymerization of dicarboxylic acid compound(s) and bisphenol compound(s), and preferably has no halogen atom in its chemical structure. According to the invention, high productivity of the optical film can be achieved since the polyester has a high solubility in solvents, and an environmental loading for production can be reduced.

The present invention provides an optical film exhibiting wavelength dispersion such that a retardation value is smaller on the shorter wavelength side, and capable of being also formed comparatively thinly.The optical film of the present invention is an optical film including a polyimide-based polymer represented by the following general formula (I).In the formula (I), m is 40% by mol or more and 100% by mol or less. R1 and R2 each independently denote a substituent having a carbon-carbon double bond or a triple bond. A, A′, B, B′, E, G, and H each denote a substituent, and small letters corresponding to these alphabets denote substitution number thereof. X and Y each independently denote bond part such as a covalent bond. The substituents having a carbon-carbon double bond or a triple bond represented by R1 and R2 are a substituted or unsubstituted aryl group, a substituted or unsubstituted vinyl group, and a substituted or unsubstituted ethynyl group.

摘要:
The invention relates to an optical film containing polymers having different repeating units, and methods for production thereof. Further, the invention also relates to an optical laminate, a polarizing plate, and an image display device each using the optical film.The optical film of the invention advantageously has not only high solubility in solvents but also a high level of transparency since the polymers used in the optical film are compatible with each other. Further, wavelength dispersion of the birefringence of the optical film can be controlled by merely changing a ratio of polymers.
