実験手順

272 ml. of water, 10 g. of Gelvatol 1-90 polyvinylalcohol and 5 g. of Acrysol WS-32 acrylic polymer were heated until the binders dissolved. 50 g. of stearic acid was then added and melted to form a liquid layer floating on the aqueous solution. 23 ml. of ammonium hyroxide (28% solution), which was the stoichiometric amount to form ammonium stearate, was then added dropwise to the gently stirred liquid. An intractable gel is formed which was transferred to a vigorously-stirred Waring Blendor, and then 20 g. of calcium chloride dissolved in 20 ml. of water slowly added until the mixture became solid. 50 ml. of water was then added with stirring until a creamy paste formed. After drying on a substrate this material gave a pressure-sensitive film with excellent hiding power. The formation of ammonium stearate in situ is the preferred method of preparation because it allows a higher solids content to be obtained and yields smaller particles of calcium stearate. The density of the dry coating was 0.5 g./cc which is equivalent to about 50% void volume.
