    摘要： Provided is a novel ion-pair charge-transfer complex polymer suitable for use as a photo-functional material which shows extremely fast photoresponses in the wide wavelength range from visible to near infrared regions, and thermally stable, wherein the acceptor is a substituted bipyridinium cation expressed by the formula (I) below. In the formula, X represents a group bonded at the 4- or 2-position relative to the nitrogen atoms of the bipyridinium group and selected from the group consisting of phenyl, biphenyl, thienyl, bithienyl, terthienyl, furyl, fluorenyl, pyrenyl, perylenyl, and vinyl groups, or X may not be present so that the pyridinium groups are directly connected; and Z represents a polymer preferably from the ring-opening polymerization of an oxazoline derivative (e.g. one substituted with phenyl group). The anion as the donor is selected, for example, from chloride, bromide, iodide, tetraphenylborate or derivatives thereof.

    摘要： A resist composition includes a base material component and a fluorine additive component. The fluorine additive component contains a fluororesin component having a structural unit containing a base dissociable group. The base material component contains a structural unit containing an acid-decomposable group in an amount of 30 mol % or more and an amount of 10 mol % or more of a resin component having a structural unit represented by formula (a10-1): where R is a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, or a halogenated alkyl group having 1 to 5 carbon atoms, Yax1 is a single bond or a divalent linking group, Wax1 is a (nax1+1) valent aromatic hydrocarbon group, and nax1 is an integer of 1 to 3.

    摘要： A method for preparing a light-colored indene-coumarone resin is here disclosed which comprises the step of polymerizing an aromatic coal fraction raw material having a boiling point of 140.degree. to 240.degree. C. in the presence of a Friedel-Crafts type catalyst in a polymerization reactor in which the amount of oxygen is restricted to 15 ml or less with respect to 100 g of the aromatic coal fraction raw material oil at room temperature. As a raw material, a mixture is also used which is composed of the above-mentioned aromatic coal fraction and a phenol in an amount of 3 to 30 parts by weight with respect to 100 parts by weight of the aromatic coal fraction.
