PURPOSE:The titled resin composition having both improved transparency and heat retaining properties, obtained by blending a thermoplastic resin with a specific amount of magnesium hydroxide satisfying specific conditions such as BET specific surface area, etc., treated with a surface treatment, as an infrared absorber. CONSTITUTION:(A) 100pts.wt. thermoplastic resin e.g., PE, PP, PVC, etc.) is blended with (B) 1-20pts.wt. magnesium hydroxide having (i) 2-15m<2>/g, preferably 5-10m<2>/g BET specific surface area, (ii) 0.3-2.0mu, preferably 0.5-1.5mu size of single crystal by electron microscopy, and (iii) >=90wt%, preferably >=95 wt% secondary particles having <=2mu particle diameter, treated with (iv) a surface treatment (sodium polyoxyethylene lauryl ether sulfate, etc.), to give the desired composition.
