Abstract
A combination of an aryl sulfonamide-formaldehyde resin and film forming material, such as cellulose acetate butyrate, which may further include a surfactant, such as a non-ionic surfactant including, for example, an alkylarylpolyether, comprises a 'universal' dispersant for resin additives, such as pigment materials. This composition generally includes 40 - 90 weight % of any of various types of additives, including pigments. The dispersant generally comprises from 30 - 80 weight % film former or binder, which may consist of cellulose acetate butyrate or a solid plasticizer, such as camphor, sucrose benzoate and dicyclohexylphthalate, and from 20 - 70 weight % of the aryl sulfonamide-formaldehyde resin. Apart from pigments, the additives may consist of fillers, extenders, etc., includng, for example, calcium carbonate, antimony oxide and magnesium silicate.
