Water developable lithographic composition

A composition for finishing, preserving and cleaning lithographic printing plates composed of a polyol having a molecular weight in the range of from about 50 to about 2,000; a maltodextrin obtained by the enzyme hydrolysis of corn or potato starch, a mixture of a C.sub.18 to C.sub.30 alcohol and an aminated, aliphatic C.sub.8 to C.sub.24 alcohol sulfate with a ratio of alcohol to sulfate ranging from about 1:1 to about 5:1; and a composition of hydrocarbons having a boiling point in the range of from about 175.degree. F. to about 500.degree. F., and a flash point of above about 100.degree. F., preferably containing 100% aliphatic components; and a substituted phenoxypoly(oxyethylene)ethanol having a hydrophile/lipophile balance of from about 8 to about 15; and a mono-, di- or tri-ethanolamine; and water; and an acid to impart a pH to the composition of from about 2.5 to about 6.5; and a buffer to maintain the pH, and preferably a bacteriostat/fungistat component.

This invention relates to a composition for use in a screen printing screen. More particularly, this invention relates to a screen printing composition comprising

Water developable screen printing composition

A process for the production of photographic images utilizing a photographic element comprising a transparent support and a coating on the support comprising a diazonium composition having a light absorbency of about 45% or less, and a colorant composition, said coating having a light transmission of not more than about 0.1%.

Process for the production of photographic images utilizing a negative

This invention relates to a resin having the general formula

Resin

An improved negative working photographic element is prepared by coating a suitable substrate with a photosensitive composition comprising an admixture of two light sensitive diazonium salts and a binder composition comprising a polyvinyl acetate resin and a styrene/maleic acid half ester copolymer. Upon imagewise exposure of the element to actinic radiation through a suitable mask, the unexposed portions are removable with an aqueous alkaline developer.
