A lithographic precursor includes a hydrophilic layer that presents a surface for lithographic interaction, and which is formulated to receive a pigment-based aqueous ink deposited (e.g., by inkjet) in an 'imagewise' pattern. The compatibility between the ink and the hydrophilic layer is such that a baking step is not required for subsequent printing.

Methods of preparing lithographic printing members by imagewise deposition and precursors suitable therefor

A water based fluid that can be utilized in a standard inkjet printer to image a lithographic printing plate. The water based fluid may include a polymer that is soluble in an alkaline aqueous media and that is resistant to neutral or acidic aqueous media. In addition, the water based fluid may include a sufficient volume of water soluble material to raise the pH level higher than 8. Further, the water based fluid may include a sufficient volume of humectant co-solvents to prevent the nozzles of an inkjet printer from drying out. The water based fluid may be used to image a lithographic plate that include an inkjet ink accepting hydrophilic layer hydrophilic properties. Various embodiments of the water based fluid advantageously allow a plate to be imaged, and then without baking or adding other chemical treatments, the plate can be immediately used for printing.

A method of forming an electrochemical cell is disclosed. The method comprises contacting a negative pole layer and a positive pole layer one with the other or with an optional layer interposed therebetween. The pole layers and the optional layer therebetween are selected to self-form an interfacial separator layer between the pole layers upon such contacting.

Oil and water repellency is conferred upon porous substrates (10) by treatment with a solution of a monomer (16) of the formula: (C.sub.n E.sub.2n+1)(CH.sub.2).sub.x (CHR)OCOCH.dbd.CH.sub.2 where n is an integer; X is 0,1,2 or 3 and R is H or CH.sub.2 --OCOCH.dbd.CH.sub.2. The monomer is polymerized in situ upon the substrate to provide a conformal coating (16') which preserves the porous structure.

The invention is a membrane comprising polymerized monomer and oligomer components. A primary membrane oligomer component is selected from acrylic polyester urethanes, and a secondary membrane monomer component is selected from 1,1,3,3-tetramethylbutylacrylamide and perfluoromonomers and perfluoroacrylic monomers. The membrane is further characterized as being microporous, permeable and having a thickness of less than 0.1 inches.

Hydrophobic microporous membrane

A gas permeable package for a preservative agent is fabricated from a material which includes a support having pores therein sufficiently large to permit passage of gas therethrough but small enough to retain a preservative agent. There is a conformal, hydrophobic and oleophobic coating on the porous support member. The coating includes a fluoroacrylate based polymer.
