The present disclosure relates to a purple dye compound for a color filter and a coloring resin composition for a color filter containing the same. The novel xanthene-based purple dye compound or the polymer dye compound obtained using the same as a monomer has superior solvent resistance and superior miscibility with a pigment in an organic solvent. Further, it exhibits superior heat resistance, chemical resistance, light resistance and brightness due to the homopolymer structure. Accordingly, a coloring resin composition containing the same can be used widely as a dye for synthetic resins and synthetic fibers, as a coloring agent for polymer materials, for a color filter used in LCDs, PDPs, etc., and so forth.
