Abstract
The invention is a water-based base material for printing inks, as well as a method for making the same, where the printing inks are primarily for use in flexographic or rotogravure printing, where the base material comprises blend vehicle and a dextrin. Additional components may be added, including but not limited to a drying retarder, a defoamer, a coalescing agent, a dispersant, water, one or more pigments or dyes, inert materials, and other materials known by those of ordinary skill in the art.
Claims23
A printing ink base material comprising dextrin and a blend vehicle, where each dextrin is a water-soluble dextrin comprising a water-soluble dietary fiber, where the average molecular weight of each dextrin is 10,000 or less, and where the blend vehicle is a water-based emulsion.
A printing ink base material comprising dextrin and a blend vehicle, where each dextrin is a water-soluble dextrin having an average molecular weight of 10,000 or less, and having a water-soluble dietary fiber content of between about 20% to about 100%, and having a pH of between about 2 to about 12, and where the blend vehicle is a water-based acrylic emulsion having an acid number of about 33, a molecular weight of between about 300,000 to about 700,000, a weight per gallon of about 8.7 pounds, a pH of about 8.3, a Tg of about −30 ° C., a NVS of about 47.0%, and a viscosity of about 600 CPS.
A printing ink base material comprising dextrin and a blend vehicle, where each dextrin is a water-soluble dextrin having an average molecular weight of vehicle is a water-based acrylic emulsion having a pH of about 7.5, a NVS of about 47.5%, a viscosity of about 1500 CPS, a Tg of about −9 ° C., a molecular weight in excess of 200,000, an acid number of about 57, and a weight per gallon of about 8.7 pounds.
