The present invention discloses a hand tool rack comprising main frame, positioning members and cover frame. A gate device is also included, wherein the gate device is configured to selectively control the flow of toner from the secondary toner reservoir to the primary toner reservoir. Since transmission is made such that a portion of signature image coefficients is superimposed on that of host image coefficients. The aligning casing is provided on the top of the insulating body. The brightness of the transflective LCD device is thus improved. As a result, the photoresist polymer and the photoresist composition containing the same have excellent transmissivity, etching resistance, thermal resistance and adhesive property, low light absorbance and high affinity to an developing solution at a wavelength of 13 nm as well as 248 nm and 157 nm, thereby reducing line edge roughness.
