Abstract
PURPOSE: To prepare an extender pigment capable of affording coating film of high gloss or ink film, by specifying a sediment volume, in cellosolve, of CaCO3 coated with a phosphoric acid type surfactant.
CONSTITUTION: (1) An 1W70 wt% aqueous suspension of CaCO3 with an average size of 0.02W2μm accounting for 90.0W99.95 wt%, and (2) a 10.0W0.05 wt% aqueous solution of a phosphoric acid type surfactant of formula I or II ( R is higher alkyl or higher alkylaryl; n is 1W50), having a HLB-value of 6W18 are mixed, followed by blowing a CO2 gas while heating at 5W80°C to make a PH- value of the mixture lower than that of the aqueous suspension, thus coating the CaCO3 surface with the surfactant. The resulting system is dewatered by pressing, dried, and ground to obtain the objective pigment having sediment volumes, in 98.1 ml cellosolve, of 90 ml/5g or more and 10 ml/5g or less, after one-hour standing and 120 hrs standing, respectively.
