Claim 1

A METHOD OF PREPARING NEWS INK OR LIKE HAVING A DESIRED PIGMENT CONCENTRATION IN THE RANGE OF ABOUT 5 TO 15% BY WEIGHT TOGETHER WITH A SELECTED VISCOSITY DESIRED FOR THE PRINTING OF THE INK, IN THE RANGE OF ABOUT 15 TO 40 POISES AS MEASURED AT 80*F. BY A BROOKFIELD RVF VISCONISMETER USING SPINDLE NO. 4 AT 20 R.P.M., WHICH COMPRISES MECHANICALLY DISPERSING CARBON BLACK AT A CONCENTRATION AT LEAST EQUAL TO SAID DESIRED PIGMENT CONCENTRATION IN A LIQUID VEHICLE CONSISTING ESSENTIALLY OF MINERAL HYDROCARBON OIL, IN THE PRESENCE OF LESS THAN 1% BY WEIGHT OF MOSITURE SAID OIL COMPRISING THE PRODUCT OF THE REACTION AT AN ELEVATED TEMPERATURE BELOW 300*F. OF A MINERAL HYDROCARBON OIL CONTAINING POLAR PETROLEUM COMPOUNDS AND HAVING AN ACID NUMBER OF 0.1 TO 5, WITH A SUBSTANCE SELECTED FROM THE GROUP CONSISTING OF THE ALKALI METALS, CALCIUM, BARIUM AND STRONTIUM AND ALKALINE REACTING COMPOUNDS THEREOF AND OF AMMONIUM, IN AN AMOUNT EQUIVALENT IN NEUTRALIZING POWER TO 0.01 TO ABOUT 0.5% OF NAOH, BASED UPON THE WEIGHT OF SAID OIL, THE AMOUNT OF SAID REACTION PRODUCT BEING SUFFICIENT TO GIVE THE DISPERSION FORMED A VISCOSITY SUBSTNATIALLY BELOW THAT OF A COMPOSITION MADE THE SAME WAY BUT WITH THE OIL NOT REACTED WITH SAID ALKALINE SUBSTANCE.
