A flame-retardant chlorine-containing resin composition is obtained by blending components (A), (B), and (C), and additionally component (D) if necessary, into a chlorine-containing resin: Component (A): a (poly)phosphate compound represented by the following general formula (1); Component (B): a (poly)phosphate compound represented by the following general formula (3); Component (C): wood flour; and Component (D): zinc oxide. In the formula (1), n represents a number from 1 to 100; Xrepresents e.g. a triazine derivative represented by the general formula (2); and 0&#x3c;p&#x2266;n+2. In the formula (2), Zand Zeach represent e.g. a &#x2014;NRRgroup. In the formula (3), r represents a number from 1 to 100; Yrepresents e.g. [RRN(CH)mNRR]; R, R, R, and Reach represent e.g. a linear or branched alkyl group having 1 to 5 carbon atoms; m represents an integer from 1 to 10; and 0&#x3c;q&#x2266;r+2.

Flame-retardant chlorine-containing resin composition

A vinyl chloride resin composition comprising 100 parts by mass of a vinyl chloride resin, (a) 0.001 to 10 parts by mass of at least one benzotriazole compound represented by general formula (I), and (b) 0.001 to 10 parts by mass of at least one salicylamide compound represented by general formula (II): wherein R, R, R, and Reach represent a hydrogen atom, a halogen atom, a hydroxyl group, a nitro group, a carboxyl group, an alkyl group, an alkoxycarbonyl group or an alkanoylamino group. wherein R represents a hydrogen atom, an alkyl group having 1 to 12 carbon atoms or an alkoxy group having 1 to 12 carbon atoms.

Vinyl chloride resin composition

A vinyl chloride resin composition comprising 100 parts by mass of a vinyl chloride resin and a co-ground mixture of (a) 0.001 to 10 parts by mass of at least one member selected from the group consisting of an organic phosphoric ester compound and a metal salt thereof and (b) 0.001 to 10 parts by mass of a grinding aid. The composition is excellent in transparency, heat stability, and heat discoloration resistance.

An antibacterial composition for medical tools made of a vinyl chloride resin, which comprises a specific cyclic organic phosphoric ester compound and a specific pyrithione compound and has excellent antibacterial properties; and a medical tool made of an antibacterial vinyl chloride resin obtained by adding the antibacterial composition to a vinyl chloride resin.
