To provide an alcohol compound containing fewer impurities at a high yield by conducting the following steps: a hydroboration process in which a reaction mixture is obtained by reacting in a solvent a compound represented by formula (C) and a boron agent selected from a group of diborane and borane complexes; and an oxidation process in which the pH of the reaction mixture is set at 0.5 to 4, which is conducted after treating the reaction mixture with hydrogen peroxide. In the formula, A1 to A6 are each independently a hydrogen atom, methyl group or ethyl group, and X is an oxygen atom, sulfur atom, methylene group or ethylene group.

Disclosed is a toner binder which has high storage stability and can achieve both of good low-temperature fixability and good hot offset resistance (a broadened fixing temperature range). Specifically disclosed is a toner binder comprising, as constituting units, a carboxylic acid component (x) and a polyol component (y), wherein the component (x) comprises two or more kinds of dicarboxylic acids (X1), selected from among aromatic dicarboxylic acids and ester-forming derivatives of the same, in a total amount of 80 mol % or more and a trivalent or higher polycarboxylic acid (x2); the component (y) comprises a polyester resin (P) which is constituted by a polyester resin (A) comprising 80 mol % or more of an aliphatic diol (y1) having 2 to 10 carbon atoms optionally together with a linear polyester resin (B); and the storage modulus at 150° C. [G′150] of resin (A) is 20000 dyn/cm2 or more and the ratio of [G′150] to the storage modulus as 180° C. [G′180] thereof, i.e., [G′150]/[G′180], is 15 of less.

A method for producing a polymer is provided. The polymer improves variations in the content ratio and molecular weights of a copolymer's constitutional units, solvent solubility, and the sensitivity of a resist composition using such a polymer. The method includes polymerizing two or more monomers while adding with a polymerization initiator to obtain the polymer, feeding a first solution containing first composition monomers in an initial polymerization stage, and starting dropwise addition of a second solution containing second composition monomers after or simultaneously with the feeding of the first solution. The second composition is equal to a target composition ratio of the polymer to be obtained. The first composition is calculated in advance based on a target composition ratio and the reactivity of the monomers. The above dropping rate is set to high.

摘要:
Plate-image-inspection RIP data CD2, CD3 are prepared using the same RIP processing conditions from two print image data prepared in different steps of the prepress process, and inspection results are obtained by comparing these data CD2, CD3. Plate-image-inspection RIP data CD2, CD3 can be prepared in several methods: (1) a method for RIP processing respective non-RIP data using standard RIP processing conditions; (2) a method for respectively converting two RIP data to standard RIP processing conditions; and (3) a method for converting one of two RIP data such that it conforms to the RIP processing conditions of the other.
