The reflectance of this paste is compared with a similar paste based on an internationally accepted standard tint reference black (ITRB #3).
The blacks had surface area (CTAB) from 31 to 44 [m.sup.2]/g, structure (DBP) from 65 to 140 ml/100g (CDBP = 61-90 ml/100g), and TINT from 46-64% ITRB. The analytical properties of this set of blacks are listed in table 1.
The analytical properties characterizing the blacks, summarized in table 1, are [I.sub.2] No (D1510) from 38 to 54 mg/g and CTAB (D3765) from 30 to 44 [m.sup.2]/g as measures of area (particle size), DBPA (D2414) from 65 to 140cc/100g and CDBPA (D3493) from 61 to 90cc/100g as measures of aggregate structure and tint (D3265) from 46 to 64% ITRB as a measure of aggregate size.
