摘要： The remover solution of the invention comprises (A) from 35 to 80% by weight of an alcoholic solvent such as ethylene glycol monoethyl ether, (B) from 10 to 40% by weight of an organic solvent which is a halogenated hydrocarbon solvent, e.g., 1,2-dichlorobenzene and methylene chloride, an ether solvent, e.g., tetrahydrofuran, or an aromatic solvent, e.g., benzene and xylene, and (C) from 0.1 to 25% by weight of a quaternay ammonium compound such as tetramethyl ammonium hydroxide and trimethyl hydroxyethyl ammonium hydroxide. Different from conventional remover solutions which only can swell cured photoresist compositions, the inventive remover solution has a power to completely dissolve a cured photoresist layer to give a quite satisfactory result in the removing works of patterned photoresist layers in the manufacture of semiconductor devices.

摘要： A water-based photopolymerizable resin composition is disclosed which is suitable for the preparation of a relief printing plate by the photolithographic techniques. The inventive composition, which basically comprises a water-soluble polymer, e.g., poly(vinyl alcohol), a photopolymerizable monomer and a photopolymerization initiator, is characterized in that at least a part of the photopolymerizable monomer is N-tetrahydrofurfuryloxymethyl acrylamide or N-tetrahydrofurfuryloxymethyl methacrylamide. By virtue of this unique ingredient in the composition, the printing plate prepared from the inventive composition is imparted with improved fidelity of pattern reproduction and durability in printing as a consequence of increased hardness and pliability to be freed from the drawback of crack formation in printing even on a cylinder of small diameter under a cold and low-humidity condition.
