Abstract
Improvements introduced in the object of the main patent for the preparation of developer compositions for revealing light-exposed surfaces of initially linear photosensitive developer-soluble synthetic linear polyamide compositions, composed of photo-insolubilized zones and developer-soluble zones, comprising a solution of calcium chloride in an alkanol selected from the group consisting of methyl and ethyl alcohol, the concentration of the solution being chosen between the limits between about 0.25 and 150 g. Of calcium chloride per liter of alcohol to achieve the development at a speed of at least 0.0125 mm. Per minute. (Machine-translation by Google Translate, not legally binding)
