Abstract: PROBLEM TO BE SOLVED: To provide a production method to produce easily and with high accuracy a polyimide thin film which is used for a medical instrument and the medical instrument equipped with the above polyimide thin film. SOLUTION: This invention is the medical instrument which includes a coating layer made of a photo-curing polyimide resin composition having (a) a polyimide resin, (b) a carbon cluster and/or its derivative and (c) a compound which includes a heterocycle excluding the above (a), or (a-1) a polyimide resin which includes a heterocycle and (b) the carbon cluster and/or its derivative as essential ingredients, and a production method of the medical instrument wherein a base material is coated with the photo-curing polyimide resin composition and irradiated with light to form the coating layer with a thickness of 1-1,000 μm.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyamic acid good in liquid crystal aligning when made into a liquid crystal film, and useful as a liquid crystal aligning agent with a wide pretilt angle by reaction between a specific tetracarboxylic acid dianhydride and a specific diamine compound. SOLUTION: This polyamic acid is obtained by reaction between (A) a tetracarboxylic acid dianhydride including a compound of formula I (R1 is a 5-30C alkyl, halogen, 1-30C haloalkyl or a univalent organic group having steroidal skeleton; X is a single bond or bivalent bond group; R2 and R3 are each H or a univalent organic group; (a) is 1-4; (b) is 0-3) and (B) a diamine compound of the formula H2N-R4-NH2 (R4 is a bivalent organic group). By the way, the compound of formula I is prepared by ene reaction between maleic anhydride and the reaction product formed by Diels-Alder reaction between maleic anhydride and a styrene derivative of formula II.
