EFFECTIVE MATTING AGENT BASICALLY CONSISTING OF PRECIPITATED SILICIC ACID

PROBLEM TO BE SOLVED: To exhibit improved matte finish effect in the case that a matting agent has the same silicic acid content ratio by mass as the conventional one. SOLUTION: The precipitated silicic acid is controlled to have 350-550 m2/g BET, 320-400 g/100g DBP number, 5-15 μm d50and 20--90 g/L...
