In particular, attempts have been made to make styrene-based resins having excellent transparency flame-retardant. In general, halogen-based flame retardants and inorganic oxides are used in combination for flame retardancy of styrene-based resins.If transparency is important, for example, a method using only inorganic flame retardants or a specific halogen-based flame retardant And a method using an inorganic oxide in combination.

になる傾向があった。However, when the above-mentioned inorganic flame retardant is used, it is necessary to add a large amount to the resin in order to obtain sufficient flame retardancy. There is a problem that the mechanical characteristics are impaired. When a halogen-based flame retardant and an inorganic oxide are used in combination, transparency tends to be sacrificed in order to obtain sufficient flame retardancy.

As a result, they have found that a flame retardant resin composition having excellent transparency can be obtained by blending a specific halogen-based flame retardant and a phosphorus-based flame retardant with a styrene-based resin, and have completed the present invention. .
