Dispersion—> blacker blacks How can you get blacker blacks? S i m p l e — add a b l u i s h - p u r p l e d y e toner. Not so simple—if you're try ing to do this with carbon paper " i n k . " This dye toner is not readily dispersible in the molten mixture of carbon black, ink oil and vegetable waxes at 175-190° F. However, it disperses easily if you mix one part of the dye toner with
two parts of Armour's Neo-Fat® 94-04 oleic acid and add t h i s i m p r o v e d toner to the carbon paper ink. The "business e n d " of the carbon paper shown above will then produce "blacker" black impressions. Neo-Fat 94-04 is also used in the manufacture of liquid metal polishes, textile conditioners, plasticizers and solubilizers.
If you have a tough job of dispersion with some other product, find out what one of the Neo-Fat fatty acids can do for you. Scarcely a business cannot find ideas . . . and profits . . . in the long list of Armour chemicalsfor-industry.
