The specification discloses a lithographic ink vehicle containing an addition copolymer of ethylenically unsaturated monomers having a critical calculated second order transition temperature (T.sub.g), and a critical molecular weight, utilizing as the essential solvents in the ink a predominantly aliphatic hydrocarbon having a kauri-butanol value of between about 18 and 31, preferably between about 21 and 28, in which the polymer must be soluble. Among the preferred monomers are isobornyl methacrylate and isobutyl methacrylate. Other ethylenically unsaturated monomers may be included, particularly functional monomers in small amounts having acid or amine groups.

Lithographic ink vehicle containing addition polymer and aliphatic

Aqueous, solution or emulsion, and solvent based compositions comprising a crosslinked vinyl addition polymer having methacrylaldimine crosslinking groups are useful as coatings, binders and adhesives. The polymers are prepared from a crosslinkable composition comprising (A) a vinyl addition homopolymer or copolymer of methacrolein and (B) a compound having at least two amine-function groups selected from primary amine and primary amine-generating groups. A method of use is described in which crosslinking is at ambient temperatures.

Amine crosslinked methacrolein copolymers for coatings, binders and

.beta.-Hydroxyalkylamide polymers are disclosed as self-curing by means of carboxy or anhydride functions in said polymers. The polymers are effective in solution, aqueous emulsion and powder coating formulations.

Self-curing copolymers containing both hydroxyamide functions and

.beta.-Hydroxyalkylamide polymers are disclosed as curable by nonpolymeric compounds having carboxy or anhydride functions. The .beta.-hydroxyalkylamide polymers are prepared either from known compounds or may be prepared by treating an ester group with an appropriately substituted amine. The polymers are useful in organic solvent solution, aqueous systems, and powder coating formulations.
