Abstract: A substrate with a thin film, including the thin film including a Si—R1 group of a compound represented by Formula (1), and the substrate including the thin film including the Si—R1 group, the thin film being disposed on a surface of the substrate, where in Formula (1), R1 represents a monovalent organic group that bonds to Si; R2 represents a monovalent organic group that bonds to Si; R3 represents an alkoxy group, an acyloxy group, or a halogen atom that bonds to Si; n represents an integer from 0 to 2; when n is 2, R2 may be the same or different; when n is 0 or 1, R3 may be the same or different; and when n is 1, R1 and R2 may bond together to form a ring structure. Si(R1)(R2)(R3)3-n??. . .

Abstract: A resist underlayer film-forming composition capable of reducing occurrence of defects caused by microparticles or the like that may be generated during formation of a coating film. A silicon-containing resist underlayer film-forming composition including: [A]a polysiloxane; [B] a glycol compound having a normal boiling point of 230.0° C. or higher and being of the following Formula (1): (wherein R1 and R2 are each independently a hydrogen atom, a C1-4 alkyl group, or a C3-4 acyl group; and n is an integer of 3 or more); and [C] a solvent (except for a compound corresponding to the compound [B]).

Abstract: The objective of the present invention is to provide a repellent which has a selectivity. Specifically, the repellent does not cause damage to an Apidae bee but suppresses the aggression of a Vespidae wasp and prevents a Vespidae wasp from coming close and building a nest. Also, the objective of the present invention is to provide a method for repelling a Vespidae wasp. The Vespidae wasp repellent according to the present invention is characterized in comprising a compound represented by the following formula (I) as an active component: wherein R1 is hydrogen atom or the like, X is a C1-4 alkylene group or the like, ? is a substituent, n is an integer of 0 or more and 5 or less.
