The present invention provides: a gas separation method which is capable of desirably separating a slight amount of a component from a mixed gas under mild conditions such that the pressure difference between both sides of a gas separation membrane is 1 atmosphere or less; and a gas separation membrane which is suitable for use in this gas separation method. According to the present invention, in a gas separation method wherein a specific gas (A) in a mixed gas, which contains the specific gas (A) at a concentration of 1,000 ppm by mass or less, is selectively permeated with use of a gas separation membrane, an extremely thin gas separation membrane that has a film thickness of 1 &#x3bc;m or less is used, so that the gas (A) is desirably separated under mild conditions such that the pressure difference between both sides of the gas separation membrane is 1 atmosphere or less.

The purpose of the present invention is to provide: a surface treatment liquid that is capable of favorably hydrophilizing or hydrophobing surfaces of an object to be treated without having to include a film forming resin; and a surface treatment method using the surface treatment liquid. The present invention provides a surface treatment liquid which comprises (A) a resin and (C) a solvent, wherein as (A) the resin, a resin is used which has a weight average molecular weight of 100000 or more and contains a functional group I which comprises one group or more selected from the group consisting of a hydroxyl group, a cyano group, and a carboxyl group, and a functional group II which is a hydrophilic group or a hydrophobic group other than the functional group I.

Surface treatment liquid and surface treatment method

To provide a surface treatment liquid capable of making a base material including polyorganosiloxane on at least a part of a surface thereof hydrophilic stably over a long period of time, and provide a surface treatment method using the surface treatment liquid. In a surface treatment liquid including (A) resin and a (B) solvent, as the (A) resin, resin having a functional group I that is a hydroxyl group and/or a cyano group is used, and a functional group II that is a hydrophilic group other than the functional group I, and a ratio of a structural unit having an anionic group to total structural units of the (A) resin is 5 mol % or less, or resin including a cationic group including an anion moiety and a cation moiety that can be bonded to the (A) resin is used.

The present invention provides a gas-permeable membrane comprising a partial structure represented by formula (I) or formula (II), (wherein Rand Reach independently represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, an alkenyloxy group having 2 to 6 carbon atoms, an aryl group or an aryloxy group, M, Mand Meach independently represents a metal atom, m1 represents an integer, n1, n2 and n3 each independently represents an integer of 1 to 3, * represents a bonding hand), a composition for forming the gas-permeable membrane and a production process of the gas-permeable membrane.

After bringing a water-containing peeling liquid in contact with a thin flat film formed on a substrate, a support film including a cover film having one main surface thereof is laminated onto the flat film, such that the support film is in contact with the flat film, a cover film-attached laminate composed of a support film and a cover film is then separated from the substrate, and the laminate including the flat film and the support film is separated from the cover film-attached film.

Method for manufacturing laminate, and laminate

A bonded member includes at least two members. The at least two members include a first member and a second member bonded to each other. The first member has a bonded face bonded to the second member. The bonded face has a recessed portion at an outer periphery of the bonded face, to retain an adhesive. The recessed portion is open at the bonded face and an outer peripheral face of the first member. In a plan view from a direction vertical to the bonded face, an outer edge of a bottom face of the recessed portion is disposed at an inner position in an in-plane direction of the bonded face than an outer edge of the outer peripheral face of the first member.
