Patent ID: 7342062

Claim:
Colored thermoplastic molding resin composition consisting essentially of a monoazo metal complex compound containing colorant composition and a thermoplastic resin, the incidence of skin sensitization in a skin sensitization potential test, based on the maximization method, of said colorant composition being not more than 20%, the purity of said monoazo metal complex compound containing colorant composition being not less than 90% as determined by separation of the colorant composition by high performance liquid chromatography, wherein the purity corresponds to the peak area percent of the monoazo metal complex peak using detection at 313 nm, said monoazo metal complex compound containing colorant composition being a compound of the following formula (1): wherein each of R 1 through R 4 and R 6 independently represents a hydrogen atom, a normal or branched alkyl group having 1 to 18 carbon atoms, a normal or branched alkenyl group having 2 to 18 carbon atoms, a sulfonamide group, a mesyl group, a sulfonic acid group, a hydroxy group, an alkoxy group having 1 to 18 carbon atoms, an acetylamino group, a benzoylamino group, a halogen atom, or —COO—R 7 ; R 7 represents a normal or branched alkyl group having 1 to 18 carbon atoms or an aryl group having 6 to 18 carbon atoms; R 5 represents a hydrogen atom, a halogen atom, a nitro group, a carboxyl group, a normal or branched alkyl group having 1 to 18 carbon atoms, an alkenyl group having 2 to 18 carbon atoms, an alkoxy group having 1 to 18 carbon atoms, an aryl group having 6 to 18 carbon atoms, —COO—R 8 or R 8 represents a normal or branched alkyl group having 1 to 18 carbon atoms or an aryl group having 6 to 18 carbon atoms; Y represents a hydrogen atom, a normal or branched alkyl group having 1 to 8 carbon atoms, an alkoxy group having 1 to 5 carbon atoms, a nitro group, or a halogen atom; m represents an integer from 1 to 3; M represents a divalent or trivalent metal; p represents 1 or 2; (A) q+ represents H + , NH 4 + , a cation based on an alkali metal, a cation based on an organic amine, or a quaternary organic ammonium ion; q represents 1 or 2; and X represents 1 or 2.
