Patent ID: 8357482

Claim:
An organic anti-reflective layer composition comprising a light absorbent represented by the following formula 1, a polymer, a thermal acid generating agent, a crosslinking agent and a solvent: wherein A represents a substituted or unsubstituted, linear or branched, saturated tetravalent hydrocarbon group having 1 to 20 carbon atoms, a substituted or unsubstituted, linear or branched, saturated hydrocarbon group having 1 to 20 carbon atoms and containing one or more heteroatoms, a substituted or unsubstituted aromatic group having 4 to 20 carbon atoms, a substituted or unsubstituted heteroaromatic group having 3 to 20 carbon atoms, a substituted or unsubstituted alicyclic group having 4 to 20 carbon atoms, a substituted or unsubstituted heteroalicyclic group having 3 to 20 carbon atoms, a substituted or unsubstituted diaryl ether having 3 to 20 carbon atoms, a substituted or unsubstituted diaryl sulfide having 3 to 20 carbon atoms, a substituted or unsubstituted diaryl sulfoxide having 3 to 20 carbon atoms, a substituted or unsubstituted diaryl ketone having 3 to 20 carbon atoms, or a substituted or unsubstituted diaryl bisphenol A having 3 to 20 carbon atoms; R 1 and R 2 each independently represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted aryl group having 6 to 14 carbon atoms, a substituted or unsubstituted acetal group, or a hydroxyl group; wherein the composition comprises 0.1 to 5% by weight of the light absorbent, 0.1 to 5% by weight of the polymer, 0.01 to 1% by weight of the thermal acid generating agent, and 0.05 to 5% by weight of the crosslinking agent.
