Mg-Zn-Al based hydrotalcite-type particles and resin composition containing the same

摘要

Mg-Zn-Al-based hydrotalcite-type particles comprise core particles composed of Mg-Al-based hydrotalcite and an Mg-Zn-Al-based hydrotalcite layer formed on the surface of the core particle, and have an average plate surface diameter of 0.1 to 1.0 mu m and a refractive index being adjustable to a required value in the range of 1.48 to 1.56; and a resin composition contains the Mg-Zn-Al-based hydrotalcite-type particles. The Mg-Zn-Al-based hydrotalcite-type particles can exhibit a large plate surface diameter and an appropriate thickness whose refractive index is adjustable to various values, and the resin composition can show not only higher resin stability and functional properties, but also an excellent transparency as compared to those using conventional hydrotalcite-type particles.
