Abstract
A photosensitive composition of a developable relief precursor includes at least one copolymer as component C, at least one ethylenically unsaturated compound as component U, at least one photoinitiator or photoinitiator system as component P, and at least one water soluble and/or water dispersible binder as component B. The at least one copolymer as component C is an at least partially hydrolyzed ethylene vinyl acetate copolymer, including CH2—CH2— groups, and the content of the CH2—CH2— groups in the partially hydrolyzed ethylene vinyl acetate copolymer is lower than 20 mol %, preferably lower than 15 mol %, more preferably lower than 10 mol %.
Claims21
A photosensitive composition of a developable relief precursor, wherein said developable relief precursor is a developable printing plate, comprising:
- at least one copolymer as component C,
- at least one ethylenically unsaturated compound as component U,
- at least one photoinitiator or photoinitiator system as component P, and
- at least one water soluble and/or water dispersible binder as component B,
- wherein the at least one copolymer as component C is an at least partially hydrolyzed ethylene vinyl acetate copolymer, comprising —CH2—CH2— groups and wherein the content of said —CH2—CH2— groups in the partially hydrolyzed ethylene vinyl acetate copolymer is lower than 20 mol %.
A photosensitive composition of a developable relief precursor, wherein said developable relief precursor is a developable printing plate, comprising:
- at least one copolymer as component C having a degree of polymerization between 400 and 900,
- at least one ethylenically unsaturated compound as component U,
- at least one photoinitiator or photoinitiator system as component P, and
- at least one water soluble and/or water dispersible binder as component B,
- wherein the at least one copolymer as component C is an at least partially hydrolyzed ethylene vinyl acetate copolymer, comprising —CH2—CH2— groups and wherein the content of said —CH2—CH2— groups in the partially hydrolyzed ethylene vinyl acetate copolymer is lower than 20 mol %.
