Abstract: PURPOSE: To obtain a polyimide which is essentially thermoplastic and has excellent properties by using a long-chain aromatic diamine composed of four benzene rings, one pyridine nucleus or benzonitrile nucleus bonded to each other through specified organic groups as a monomer component. CONSTITUTION: A hydroxy aromatic amino compound such as 2-(4- aminophenyl)-2-(4'-hydroxyphenyl)propane is condensed with a dihalogenopyridine or a dihalogenobenzonitrile to obtain an aromatic diamino compound represented by formula I (wherein L is O, carbpnyl or isopropylidene; X is a group of formula II or III; and Ar is a 6-27 C aromatic group), An aromatic diamine component based on this compound is reacted with an aromatic tetracarboxylic dianhydride to make a polyamic acid. This acid is imidated thermally or chemically to obtain a polyimide comprising repeating units of formula IV. The new polyimide which is one having a specified structure having a pyridine nucleus or a benzonitrile nucleus is essentially thermoplastic and is an injection-moldable material of excellent processability.

CONSTITUTION: A salicylic acid resin composition of formula I [Z is H, M/i (M is an i-valent metal ((i) is an integer); (n) is 0-100] is used. The compound of formula I is preferably the compound wherein Z is H or wherein M is Zn and (i) is 2. The salicylic acid resin composition of formula I is added to a substrate such as a resin coating, non-woven fabric, fiber, paper or building material especially in an amount of 0.1-2wt.%. The salicylic acid resin composition wherein Z is H is obtained by reacting a salicylic acid (ester) of formula II (R1 is an alkyl) with an aralkyl compound of formula III (X is an alkoxy, OH, a halogen). Various kinds of the substrates to which the antibacterial and antifungal properties are imparted can be used for e.g. wall paper, bathtubs, shower hoses, washing machines, refrigerators or kitchens.
