The present invention relates to a polymer resin compound including a new polycyclic compound, and a photosensitive resin composition including the polymer resin compound as an effective binder matrix. In particular, the photosensitive resin composition according to the present invention uses a polymer resin compound, which includes a compound having double cyclic structure in one molecule as a monomer, as a binder matrix. Accordingly, the photosensitive resin composition has an excellent photosensitivity and an excellent developing property, and has a low distortion property during plastic processing. For this reason, the photosensitive resin composition has an advantage of curing various transparent photosensitive materials used to manufacture a color filter of a liquid crystal display, for example, a column spacer, an overcoat, a passivation material, and the like.

The present invention relates to a dendritic photoactive compound that comprises oxime ester and a method for producing the same. Since the compound according to the present invention comprises two or more oxime ester groups and chromophores in one molecule at the same time, the solubility in respects to the organic solvent and the efficiency for producing a radical by absorbing ultraviolet rays are excellent. In addition, it can act as an effective initiator in respects to the photopolymerization of the unsaturated group, in particular, the acryl compound.
