    摘要: A developer composition for photosensitive coatings on substrates, particularly lithographic printing plates sensitized with substantially water-insoluble diazonium compounds, which is comprised of an aqueous solution of an amphoteric surfactant and a substantially water-soluble organo-lithium salt, e.g., lithium naphthenate, lithium benzoate, lithium ricinoleate, etc. The novel developers quickly remove non-image areas of the plate and yet do not detrimentally dissolve the image areas of the plate.

    摘要: A METHOD FOR MAKING A STORAGE-STABLE, MOISTURE-RESISTANT, LIGHT-SENSITIVE DIAZONIUM COMPOUND IN DRY POWDER FORM BY REACTING A LIGHT-SENSITIVE, WATER-SOLUBLE DIAZO COMPOUND WITH A HYDROXYL-CONTAINING COUPLING AGENT THEREFOR IN AN AQUEOUS MEDIUM AT A PH OF ABOUT 1.5 TO ABOUT 7.5 SUBSTANTIALLY TO AVOID RESINIFICATION AND LOSS OF LIGHT-SENSITIVITY, AND RECOVERING THE PRECIPITATED DIAZONIUM COMPOUND REACTION PRODUCT.
