Abstract: The present invention provides a process for producing a practical toner for the development of an electrostatic image which has an effect of preventing an offset phenomenon and has low-temperature fixing properties. The process for producing a toner of the present invention comprises the steps of dissolving a high-molecular polymer in a vinyl monomer, mixing the resultant solution with another toner material, and then carrying out suspension polymerization. Preferable examples of the high-molecular polymer include a polymer having a structure unit represented by the formula ##STR1## wherein R.sup.1 is hydrogen or a methyl group, and R.sup.2 is a straight-chain or branched alkyl group having 1 to 20 carbon atoms,and a polymer having a structure unit represented by the formula ##STR2## wherein R.sup.3 is hydrogen or a methyl group, and X is hydrogen, a methyl group, a halogen atom or a methoxy group.

Abstract: A triazolo-1,4-azepine compound of the below given formulas and a pharmacologically acceptable salt thereof are disclosed and useful in the pharmaceutical field, especially to allergic diseases. ##STR1## in which R1 and R2 are hydrogen or an alkyl, R3 is hydrogen or a halogen, R4 is hydrogen or an alkyl, X is --OCO--, --NHCO--, --CO-- or others and Y is a cycloalkyl, a cycloalkylalkyl, an alkynyl or others.

Abstract: After a silicon nitride film (2) is etched by using a first resist pattern (3A) as a mask before coating a second resist (4) superposing on the first resist pattern (3A), a surface layer portion of the first resist pattern (3A) is subjected to a plasma treatment by using oxygen (O.sub.2). A properties changed layer in the surface layer portion of the first resist pattern (3A) is removed or modified to improve the adhesion between the second resist (4) and the first resist pattern (3A), and the stripping of the second resist (4) is prevented.
