Abstract:
A color developing composition for pressure-sensitive recording systems comprising an admixture of an alkylidenediphenol and calcium carbonate having a weight ratio of about 2 parts to about 20 parts phenol per 100 parts calcium carbonate. The admixture is formulated in high solids content coating colors having excellent rheological property and stabilty, which are used to produce CF sheets having a coating weight of about 4 to about 10 g/m. sub. 2. Preferably, the composition comprises Bisphenol A in an amount of 4 to 10 parts per 100 parts calcium carbonate and the calcium carbonate weight % in the CF coating is greater than 50%. Other embodiments comprise an aqueous dispersion of the admixture, a pressure-sensitive recording manifold and methods of making the dispersion.
