Abstract
A photosensitive composition in solution for printing screens which comprises: (a) a liquid medium selected from the group consisting of water-miscible organic solvents and solvent mixtures of said organic solvents and water; (b) a polymer soluble in both said organic solvents and water; and (c) a sensitizer soluble in said organic solvents which is selected from the group consisting of photosensitive monomers and prepolymers thereof. This composition makes it possible to produce presensitized printing screens of excellent preservability and printing resistance and to provide a process for efficiently producing pre-sensitized printing screens.
