摘要： The present invention is a sulfonium salt represented by the following formula (1),
wherein “p” represents an integer of 1 to 3; R11 represents a hydrocarbyl group having 1 to 20 carbon atoms; Rf represents a fluorine atom or a fluorine-atom-containing C1 to C6 group selected from alkyl, alkoxy, and sulfide; “q” represents an integer of 1 to 4; RALU represents an acid-labile group; “r” represents an integer of 1 to 4; R12 represents a hydrocarbyl group having 1 to 20 carbon atoms; “s” represents an integer of 0 to 4; “t” represents an integer of 0 to 2; Rf and —O—RALU are bonded to adjacent carbon atoms; and X− represents a non-nucleophilic counterion having no polymerizable group. This provides a sulfonium salt used for a resist composition having excellent solvent solubility, high sensitivity and high contrast, and excellent lithographic performance such as exposure latitude and LWR; a resist composition containing the sulfonium salt as a photoacid generator; and a patterning process using the resist composition.-

摘要： There are provided a porous water-soluble nonionic cellulose ether having an average pore size of 36 μm or smaller and an average particle size of from 30 to 300 μm; and a method for continuously producing said cellulose ether comprising the steps of: pulverizing a first water-soluble nonionic cellulose ether to obtain a first pulverized product, and sieving the pulverized product through a sieve having an opening of from 40 to 400 μm to obtain a first residue-on-sieve and a first sieve-passing fraction, wherein a portion or all of the first residue-on-sieve containing particles having particle sizes smaller than and greater than the opening of the sieve is re-pulverized together with a second water-soluble nonionic cellulose ether in the step of pulverizing to obtain a second pulverized product, which is pulverized to obtain the cellulose ether as a second sieve-passing fraction containing the re-pulverized particles.

摘要： There are provided hydroxypropyl methyl cellulose (HPMC) having a high solubility in an organic solvent even when it has a degree of substitution (DS) of methoxy groups and a molar substitution (MS) of hydroxypropoxy group which are the same as those in the conventional art; and others. Specifically, there are provided HPMC having the MS of from 0.1 to 0.5; a ratio (referred to as “MF at 3-position/MS”) of 0.12 or more, as calculated by dividing a molar fraction (referred to as “MF at 3-position”) of anhydroglucose units in which only a hydroxy group at the 3-position carbon is substituted with a hydroxypropoxy group and none of hydroxy groups at the 2-position and 6-position carbons is substituted with a hydroxypropoxy group by the MS; and a viscosity at 20° C. of from 1.0 to 50 mPa·s, as determined in a 2% by mass aqueous solution; and others.

摘要： There are provided hydroxypropyl methyl cellulose (HPMC) having high solubility even when keeping the molar substitution (MS) of hydroxypropoxy groups conventional; and others. More specifically, there are provided HPMC having a molar substitution (MS) of hydroxypropoxy groups of from 0.1 to 0.5, a ratio (referred to as “MF at 3-position/MS”) of 0.12 or more, as calculated by dividing a molar fraction (referred to as “MF at 3-position”) of anhydroglucose units in which only a hydroxy group at the 3-position carbon is substituted with a hydroxypropoxy group and none of hydroxy groups at the 2-position and 6-position carbons is substituted with a hydroxypropoxy group by the molar substitution (referred to as “MS”) of hydroxypropoxy groups, and a viscosity at 20° C. of more than 50 mPa·s and not more than 150000 mPa·s, as determined in a 2% by mass aqueous solution; and others.

摘要： Provided is a magnetic refrigeration material whose magnetic transition temperature has been adjusted with high accuracy and which includes at least a first predetermined magnetic refrigeration material and a second predetermined magnetic refrigeration material which differs from the first magnetic refrigeration material. The absolute value of the difference between the magnetic transition temperature of the present magnetic refrigeration material and a target magnetic transition temperature is 0.7 K or less. The content of the first magnetic refrigeration material and the content of the second magnetic refrigeration material are determined by the magnetic transition temperatures of the first magnetic refrigeration material and the second magnetic refrigeration material and by a target magnetic transition temperature of the magnetic refrigeration material.
