| titleOfInvention | Polyimide precursor modified with dicarboxylic acid anhydride, polyimide obtained by imidization, and liquid crystal aligning agent using the same |
| abstract | The present invention provides a polyimide precursor and/or a polyimide that has good solubility in various organic solvents, and can obtain a liquid crystal aligning film that is particularly good in rubbing resistance and hardly deteriorates due to irradiation of a backlight . The polyimide precursor or the polyimide obtained by imidating the polyimide precursor is characterized in that the terminal amino group is selected from at least one of the general formula [1] and the general formula [2]. Alicyclic epoxy dicarboxylic acid anhydride has been modified; in the formula, Y represents an alkylene group or an oxygen atom with 1 or 2 carbons, and R 1 represents a hydrogen atom or an organic group represented by -X 1 -X 2 -X 3 In the formula, X 1 is a single bond or -CH 2 -, X 2 is a single bond or -O-, X 3 represents an alkyl group with 1 to 20 carbons, a haloalkyl group with 1 to 20 carbons, or a cyano group Alkyl groups with 1 to 20 carbon atoms.
