  • Patent number: 7579133
    Abstract: A radiation-sensitive medium comprises hydrophilic polymer particles, the particles comprising a thermally softenable hydrophobic polymer, a hydrophilic polymer and a bonding compound capable of chemically bonding to the hydrophobic polymer and to the hydrophilic polymer. The radiation-sensitive medium further may comprise a substance capable of converting radiation into heat. The radiation-sensitive medium is aqueous-ineluable when coated and dried, and becomes hydrophobic under the action of heat. The polymer particles are made by polymerization of at least one hydrophobic monomer and at least one bonding compound in the presence of the hydrophilic polymer. The radiation-sensitive medium may be provided as a coatable composition to be applied to substrates to form a processless radiation-imageable lithographic printing precursor, which may further be provided with an aqueous eluable hydrophilic overcoat.

  • Patent number: 5116876
    Abstract: The polymerization of a cationically polymerizable resin especially an epoxy resin is effected by placing it adjacent to but not in contact with a layer comprising a photoinitiator. The preferred initiators are salts which comprise a fluorine atom such as hexafluorophosphate and tetrafluoroborate salts. The initiator may be irradiated separately which facilitates the curing of resins containing pigments. The products are free from contamination by unreacted initiator.
