Latest Patents

One of Parker's latest inventions is a photosensitive element featuring an overcoat that enhances photo-speed. This innovative element consists of a support with a surface, a photosensitive layer, and a transparent protective coating. The photosensitive layer is made from a composition of an ethylenically unsaturated compound and a photo-initiator, allowing for photo-initiated addition polymerization. The protective coating, which is PVA-based, is designed to be substantially impermeable to atmospheric oxygen. Notably, the photo-speed is significantly improved when the coating contains an acid, particularly when it has an acidic pH of less than 5.5. Additionally, the coating may include a second polymer for surface hardness and scratch resistance, along with a plasticizer to enhance flexibility and prevent cracking.

Another significant patent by Parker is a waste water cleaning system intended for use with apparatus for processing exposed lithographic plates. This system incorporates a centrifuge that effectively removes contaminants from the waste water generated during processing. The centrifuge is equipped with an inlet for receiving waste water and an outlet for discharging the cleaned water. The system also features control mechanisms to manage the operation of both the processing apparatus and the centrifuge, ensuring efficient cleaning and processing.
