<p>PURPOSE: Provided are hydroxy protected 1,4-dihydroxyanthraquinone derivatives used as a precursor of material for forming fine fluorescent image, copolymers thereof applied to material for recording and a sensor, and a process for forming the fine fluorescent image by using the copolymers. CONSTITUTION: The hydroxy protected 1,4-dihydroxyanthraquinone derivatives are represented by the formula (1), and the copolymers thereof represented by the formula (2) are produced by radical polymerizing the hydroxy protected 1,4-dihydroxyanthraquinone derivatives and comonomers selected from the group consisting of styrene, maleimide, and methacrylate in the presence of a polymerization initiator. And the process for forming the fine fluorescent image comprises the steps of: dissolving the copolymers containing the hydroxy protected 1,4-dihydroxyanthraquinone and a photoacid generator in an organic solvent; spreading the solution on a substrate and drying to from a thin film; prebaking the thin film coated substrate; treating under the condition of chemical amplification to remove the hydroxy protecting group from the copolymers. In the formula, R1 is hydroxy protecting group, one of A and B is H, R2 is O or NH, R3 is vinyl, alpha-methyl vinyl, or 4-biphenyl, one of C and D is H and the other is represented by the formula (c) or (d), R4 is hydrogen or methyl, R5 is methyloxycarbonyl or phenyl, m is an integer of 0-20, x and y are independently an integer of 10-5000.</p> |
