Abstract
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.
