摘要： Disclosed herein are novel multivalent metal-modified salicyclic acid resins useful as color-developing agents for pressure-sensitive copying paper. They can each be produced by causing a salicyclic acid ester and a styrene derivative to undergo a Friedel-Crafts reaction in the presence of a strong acid catalyst, hydrolyzing the resulting salicylic acid ester resin, and then reacting the thus-obtained salicyclic acid resin with a multivalent metal salt.

摘要： 4-Fluorobenzophenone derivatives of 4,4'-difluorobenzophenone are produced by effecting a halogen-fluorine exchanging reaction between the corresponding 4-halogenobenzophenone derivatives or 4,4'-dihalogenobenzophenone and an alkali fluoride.The reaction is carried out by heating in an organic solvent. After distilling off the solvent from the reaction product mixture, the end product is isolated by extracting with a solvent. Alternatively the end product is isolated by distillation.

摘要： Odorless or absolutely ordorless multi-valent metal-modified salicylic acid. The former copolymers are obtained by condensing salicylic acid with a benzyl aldehyde, reacting the resultant resin with a styrene derivative and reacting the resin thus-obtained with a multivalent metal salt. The latter copolymers are obtained by adding water dropwise to the resultant multi-valvent metal-modified resin at a temperature above the boiling point of water to remove completely volatile matters.
