Effect of Acyl J-Acid on the Property of the Black Line Diazo Sensitive Paper

摘要

N-acetoacetate J-acid was synthesized and as the third coupling component added to the coating solution containing the main component consisting of resorcinol and 2,3-dinaphthol-6-sulfonic acid (simplified name 2,3,6, acid), forming tri-coupling component coating solution. The black line diazo sensitive paper prepared from the new coating solution is remarkably improved in fastness to water, to sunlight and in the rate of sensitization and development.
