A composition comprising: (i) a thermoplastic resin; (ii) from 30 to 70% by weight, based on the resin composition, of magnesium hydroxide having a specific surface area of 20 m<2>/g or less and an average secondary particle diameter of 0.2 to 5.0 mu m, at least a part of the magnesium hydroxide being surface-treated with at least one surface-treating agent; and (iii) from 1 to 20% by weight, based on the resin composition, of a reaction type compatabilizing agent, the or each surface-treating agent being selected from: (a) a water-soluble silane-coupling agent; (b) a phosphoric acid ester of the formula Ä2Ü, <CHEM> wherein R is an alkyl group or alkenyl group which has from 1 to 24 carbon atoms, n is an integer of from 0 to 6, m is 1 or 2, A is an alkylene group having from 2 to 4 carbon atoms and M is an alkali metal, an alkyl amine cation having from 1 to 4 carbon atoms or an alkanolamine cation of the formula Ä3Ü, Ä(R')3-rN-(B-OH)rÜ<+> wherein R' is a hydrogen atom or an alkyl group having from 1 to 3 carbon atoms, B is an alkylene group having from 2 to 4 carbon atoms and r is an integer of from 1 to 3; and (c) a higher fatty acid and/or an alkali metal salt thereof. |
