Photosensitive polymer composition containing a soluble polymer of islands-in-a-sea structure, a photopolymerizable polymer, and a photopolymerization initiator |
摘要 |
This invention relates to a photosensitive polymer composition containing as essential components (A) a soluble polymer, (B) a photopolymerizable compound having an ethylenic double bond in the molecule there of and (C) a photopolymerization initiator, the soluble polymer comprising a water-soluble polymer and an alcohol-soluble polymer, the composition having a sea-and-islands structure comprising sea containing the water-soluble polymer as a main component and islands containing the alcohol-soluble polymer as a main component, and the islands are independently in the form of sphere or oval having a diameter of 0.1 to 20 microns. The photosensitive polymer composition affords a printing plate having high image reproducibility and water-developability and capable of withstanding the coating of an aqueous polymer according to a printing method.
