Five synthetic latices have been evaluated as to their adhesive values and influence on optical properties of the coated papers.
The five synthetic polymers were acrylates, acrylonitrile-buta-diene, polyethylene, polystyrene-butadiene, and vinyl acetate.
The latices were used to substitute, on a pound per pound basis, 25, 50 and 75 percent of the casein used as binder in a standard coating color consisting of 100 parts of coating clay and 16 parts of casein.
Higher adhesive values than that of straight casein were established by acrylates and two butadiene copolymers. Vinyl acetate and polyethylene possessed lower adhesive values than straight casein color.
Outstanding optical characteristics, gloss, opacity, and brightness, were obtained by use of vinyl acetate whereas the other synthetics were either equal or inferior to casein in their performance.
