    摘要： Mg-Al-based hydrotalcite-type particles suitable as a stabilizer for chlorine-containing resins comprise:

    (a) Mg-Al-based hydrotalcite-type core particles represented by the composition formula:

            Mg 1-x ·Al x ·(OH) 2 ·A n- p ·mH 2 O



    wherein 0.2≤x≤0.6; p=x/n; A is an n-valent anion; and m is more than 0 and not more than 1; and

    (b) a coating layer on each Mg-Al-based hydrotalcite-type core particle, which comprises at least one compound selected from higher fatty acids, organosilane compounds and rosins; and having:
    (c) a plate surface diameter of from 0.3 to less than 1.0 µm,
    (d) a thickness of from 0.02 to 0.08 µm,
    (e) a heat-resisting time of not less than 160 minutes.
