Zusammenfassung:PURPOSE:To obtain the subject controlling agent, markedly improved in pitch adsorption performance and capable of remarkably reducing pitch trouble and improving quality by mixing a specific reaction secondary aggregate with talc in a specified proportion. CONSTITUTION:The objective controlling agent obtained by mixing a secondary reactional aggregate which is produced by a reaction between an acid-treated acidic clay as the secondary aggregate in the reaction and an Al salt, having >=75ml/100g oil absorption, >=2.5mum average particle diameter and >=140m /g specific surface area with talc having
