Definitions
- a coating composition which comprises a major amount of cellulose propionate and a minor amount of a compatible polyamide resin.
- the cellulose propionate contains, by weight, at least about 35% propionyl, between about 4.4% and about 12% hydroxyl and no greater than about 4.5% acetyl, and has a viscosity of between about 0.02 to 20 seconds.
- the polyamide resin is made by the polymerization of a dimeric fatty acid with one or more polyamines, and has an amine value of between about 27 and about 400.
- the cellulose propionate and polyamide resin are dissolved in a suitable solvent system and the solution is especially useful as an overprint for wet oxidizing inks.
Abstract
A COATING COMPOSITION IS DISCLOSED WHICH COMPRISES A MAJOR AMOUNT OF CELLULOSE PROPIONATE AND A MINOR AMOUNT OF A COMPATIBLE POLYAMIDE RESIN. THE CELLULOSE PROPIONATE CONTAINS, BY WEIGHT, AT LEAST ABOUT 35% PROPIONYL, BETWEEN ABOUT 4.4% AND ABOUT 12% HYDROXYL AND NO GREATER THAN ABOUT 4.5% ACETYL, AND HAS A VVISCOSITY OF BETWEEN ABOUT 0.02 TO 20 SECONDS. THE POLYAMIDE RESIN IS MADE BY THE POLYMERIZATION OF THE DIMERIC FATTY ACID WITH ONE OR MORE POLYAMINES, AND HAS A AMINE VALUE OF BETWEEN ABOUT 27 AND ABOUT 400. THE CELLULOSE PROPIONATE AND POLYAMIDE RESIN ARE DISSOLVED IN A SUITABLE SOLVENT SYSTEM AND THE SOLUTION IS ESPECIALLY USEFUL AS AN OVERPRINT FOR WET OXIDIZING INKS.
