The present invention relates to a thermoplastic copolymer resin having an excellent flame retardancy and transparency and a preparation method therefor and, more particularly, to a thermoplastic copolymer resin having an excellent balance of physical properties such as a transparency, a fluidity, a low temperature impact strength as well as a flame retardancy, a preparation method therefor, and a molded article comprising the thermoplastic copolymer resin, in which the thermoplastic copolymer resin is obtained by copolymerizing polysiloxane having a particular structure and a branched polycarbonate oligomer.

Thermoplastic copolymer resin having excellent flame retardancy and transparency and preparation method therefor

Disclosed is a portable latent fingerprint developing apparatus capable of visibly checking out an external shape of a finger print by using an UV LED lamp, after a fine spray of a fingerprint developing liquid is conducted by using a vibrator and providing the corresponding fingerprint image to an external terminal, after it is photographed by a camera.
