  • Lithographic ink vehicle containing addition polymer and aliphatic hydrocarbon solvent
    Patent number: 4388434
    Abstract: 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.

  • Amine crosslinked methacrolein copolymers for coatings, binders and adhesives
    Patent number: 4230772
    Abstract: 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.
