Pattern formation

A positive working lithographic plate precursor comprising a support having a hydrophilic surface and a coating thereon comprising a positive working, photosensitive composition and an aryl alkyl polysiloxane. A method of preparing a positive working lithographic plate precursor comprising coating on a support having a hydrophilic surface a coating comprising, in admixture, a positive working photosensitive composition and an aryl alkyl polysiloxane.

Direct positive lithographic plate

An improved hydrophilized substrate for planographic printing is disclosed. The substrate contains a support and a hydrophilic layer over the support. The hydrophilic layer contains titanium dioxide (titania) particles. In one embodiment, the hydrophilic layer contains a mixture of coated and uncoated titanium dioxide particles, and, optionally, alumina particles. A method for preparation of the substrate and a printing member comprising the substrate are also disclosed.
