<p>Planographic printing plates are made by depositing on a support sheet an aqueous mixture comprising a hydroxyl group-containing polymer free from acid groups, an insolubilizing agent, a synthetic polymer containing acid groups and preferably a filler, and then drying the deposited layer. The process can be operated at near ambient temperature to give rapidly and reliably a durable water-insoluble hydrophilic layer.</p> |
