Abstract

Light-sensitive compositions comprise soluble modified epoxy resins obtained by reacting a chlorosulphonyl or chlorocarbonyl substituted azidoaryl compound with a polycondensate of a bisphenol with epichlorohydrin. The modification is performed in the presence of pyridine and, optionally, of methylene dichloride as a solvent. After dilution of the reaction mixture with methylene dichloride the product is recovered by precipitation with methanol. The compositions preferably contain organic solvents and photosensitizers. The compositions are photochemically cross-linked on exposure to actinic light.ALSO:p-Azidobenzoic acid is prepared by adding aqueous NaNO2 and NaN3 successively to a cold solution of p-aminobenzoic acid in strong hydrochloric acid and filtering off the precipitate p-Azidobenzoyl chloride is obtained by reacting the acid with SO2Cl2. Sodium p-azidobenzenesulphonate is prepared by dissolving sulphanilic acid in aqueous Na2CO3, cooling, and adding successively aqueous NaNO2, aqueous HCl and aqueous NaN3. The product is precipitated by the addition of NaCl. p-Azidobenzenesulphonyl chloride is obtained from the sodium salt by reaction with SO2Cl2.
