A disc cartridge includes a cartridge body, a first shutter, a second shutter, and a rotational member. The protective cover can be attached to the exterior of a handbag by various mechanisms and can comprise one or more carrying straps. The composition allows the overlying photoresist film to be patterned to a satisfactory profile and has a high etching selectivity relative to organic materials. The target Raman data set is transformed into a vector space defined by the pre-determined vector space. Compounds of particular interest are defined by Formula I wherein Q, R1, R2, R3 and R4 are as described in the specification.
