The present invention provides a resin composition and the mold goods formed by thereof. The mold goods produced by using the resin composition of the present invention could effectively mask the heat ray from the sun and also is superior in transparnancy. The resin composition includes the aromatic polycarbonate resin (ingredient A); the hexaboride particles (ingredient B-1) having at least one element selected from the group consisting of Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sr and Ca; and the resin other than ingredient A. The total content of (B-1) and (B-2) is in the range of 0.001 to 1 parts by weight based on 100 parts by weight of (A). The resin composition comprises the particle (1) formed by (B-1) and the particle (2) formed by (B-1) and (B-2). The number average particle diameter of particle (1) and particle (2) both are less then 50 μ m, and the maximal secondary average particle diameter is less then 300 μ m. |
