Abstract
1,213,835. Montmorillonite clay minerals. MIZUSAWA KAGAKU KOGYO K.K. 14 Nov., 1968, No. 54042/68. Heading C1A. [Also in Division D2] Acid-treated dioctahedral montmorillonite clay minerals and mixtures of said minerals with natural dioctahedral montmorillonite clay minerals, having a specific surface area of at least 180 m.<SP>2</SP>/g. and a secondary colour development property (defined) of at least 1-40, at least 75% by weight of the total particles having a diameter of 10 microns or less, and at most 45% by weight of the total particles having a diameter of 1 micron or less, are used as a colour former for pressure-sensitive recording paper. The primary colour development property (defined) of the colour former is preferably at least 2-60 and suitable specified dioctahedral montmorillonite clays are bentonite, subbentonite, Japanese acid clay, fuller's earth and Florida earth. The Specification refers to processes of grinding and classification to produce materials having the desired particle size; the acid treatment may be carried out with hydrochloric or sulphuric acid.
