ABSTRACT:
A photo-crosslinkable resin composition comprises (a) a polymer having an electron-donating group in a monomer unit, (b) a halogen compound, (c) an onium salt and (d) at least one sensitizer selected from the group consisting of coumarin derivatives, rhodanine derivatives, thioxanthene derivatives and unsaturated cyclopentanone compounds. The composition can be used as a hologram recording medium.
