Abstract
A resinous binder formulation is disclosed which relates to binders containing dilution-enhancing polymers for "letdown" metal resinate vehicles in publication gravure printing inks. The resinous binder comprises a metal resinate, and a dilution-enhancing polymer selected from the group consisting of polymers of maleic anhydride and ethylene and polymers of acrylonitrile, butadiene, acrylic acid and/or methacrylic acid. The dilution-enhancing polymer being present in the resinous binder in an amount which is effective to increase the dilution of the resinous binder in aromatic and nonaromatic solvents. Also disclosed is a publication gravure ink comprising a mixture of a solvent, a colorant and the resinous binder.
Claims53
A resinous binder comprising;
- (a) a metal resinate, and
- (b) a dilution-enhancing polymer selected from the group consisting of
- copolymers of maleic anhydride and ethylene and copolymers of
- acrylonitrile, butadiene, acrylic acid and/or methacrylic acid, wherein the dilution-enhancing polymer is present in the resinous binder in an amount which is effective to increase dilution of the resinous binder in aromatic solvents and in nonaromatic solvents as compared to the dilution of the metal resinate alone.
A publication gravure ink comprising a mixture of;
- (i) a solvent,
- (ii) a colorant, and
- (iii) a resinous binder comprising;
- (a) a metal resinate, and
- (b) a dilution-enhancing polymer selected from the group consisting of copolymers of maleic anhydride and ethylene and copolymers of acrylonitrile, butadiene, acrylic and/or methacrylic acid,
- wherein the dilution-enhancing polymer is present in the resinous binder in an amount which is effective to increase the dilution of the resinous binder in aromatic and nonaromatic solvents as compared to the dilution of the metal rosin resinate alone.
