Abstract
A positive-working light-sensitive composition is herein disclosed, which comprises a mixed organic solvent consisting of (i) at least one organic solvent having a boiling point of at least 40.degree. C. and less than 100.degree. C., (ii) at least one organic solvent having a boiling point of at least 100.degree. C. and less than 140.degree. C., and (iii) at least one organic solvent having a boiling point of at least 140.degree. C. and less than 210.degree. C.; or (a) at least one organic solvent as defined in the above item (i), (b) at least one organic solvent as defined in the item (ii), (c) at least one organic solvent having a boiling point of at least 210.degree. C., and optionally at least one solvent as defined in the item (iii), based on the total weight of the mixed solvent, the composition making it possible to extremely reduce load for drying and to impart excellent properties such as development latitude to the resultant light-sensitive layer and the composition being useful to produce PS plates according to a continuous process.
