An optical patterning composition using a hyperbranched polymer is provided. [Solution] The photo-patterning composition using the hyperbranched polymer of the present invention comprises a radical polymerizable monomer A having two radical polymerizable unsaturated double bonds in the molecule, an acid-decomposable group and one radical in the molecule. The radical polymerizable monomer B having a polymerizable unsaturated double bond is used in an amount of 5 to 200 mol% of the polymerization initiator C based on the total number of moles of the radical polymerizable monomer A and the radical polymerizable monomer B. It contains a hyperbranched polymer obtained by polymerizing in the presence. [Selection figure] None |
