摘要:
A recording material for producing offset printing plates includes: a support having a hydrophilic surface, and an infrared-imageable layer including a) a component which is capable of absorbing infrared radiation and converting the infrared radiation to heat, b) a compound which is capable of releasing acid under the action of the heat generated by component a), and c) a polymeric binder having at least one group which is cleaved by the acid released from the compound b), and at least one hydrophilic group, and wherein the layer becomes soluble in an aqueous-alkaline developer in areas struck by infrared radiation.
