Abstract:
Provided is a water-swelling layered double hydroxide characterized by having an organic sulfonic acid anion (A−) between layers, and by being represented by the below mentioned general formula (1): QZR(OH)2(Z+1)(A−)(1−y)(Xn−)y/n.mH2O . . . (1). Here, Q is a divalent metal, R is a trivalent metal, A− is an organic sulfonic acid anion, m is a real number greater than 0, and z is in the range of 1.8≦z≦4.2. Xn− is the n-valent anion remaining without A− substitution, n is 1 or 2, y represents the remaining portion of Xn−, and 0≦y
