Embodiment

[0639] Hereinafter, the present invention will be described in further detail through examples, but the present invention is not limited thereto.

[0640] The meanings of symbols and abbreviations in Examples are shown below.

[0641] PEI: polyethyleneimine

[0642] The epoxy derivative (Ex1) used in Production Examples 1-1 and 1-2 described later is

[0643] 【Chemical 5】

[0644]

[0645] The epoxy derivatives (Ex2) used in Production Examples 2-1 and 2-2 described later are

[0646] 【Chemical 6】

[0647]

manufacture example 1-1P

[0648] Manufacture Example 1-1 Manufacture of PEI-Ex1 film 1

[0649] The number average molecular weight is 0.75×10 6 0.1 ml of a 15 wt % aqueous solution of branched polyethyleneimine was spin-coated (2500 rpm, 100 sec) on a glass substrate to prepare a PEI film.

[0650] 0.03 ml of a methanol solution (Ex1) of an epoxy derivative was dropped on the PEI film, and a cover glass was covered thereon.

[0651] This was heated at 120°C for 30 minutes.

[0652] Place at room temperature, after cooling to room temperature, remove the cover glass, wash the aforementioned thin film with THF, and dry it under reduced pressure to obtain a PEI-Ex1 thin film (thickness: less than 10 nm).

manufacture example 1-2P

[0653] Manufacture Example 1-2 Manufacture of PEI-Ex1 Film 2

[0654] Make the number average molecular weight 0.75×10 6 The 15wt% aqueous solution of the branched polyethyleneimine and the methanol solution (Ex1) of the epoxy derivative were reacted at 80° C. for 12 hours.

[0655] The solvent was distilled off using an evaporator, and dried under reduced pressure to obtain PEI-Ex1.

[0656] This PEI-Ex1 was dissolved in methanol, and 0.1 ml of this solution (10 wt%) was spin-coated (2500 rpm, 100 sec) on a glass substrate to prepare a PEI-Ex1 thin film.

[0657] The aforementioned thin film was washed with THF, and dried under reduced pressure to obtain a PEI-Ex1 thin film (film thickness: 10 nm or less).

Abstract

The present invention addresses the problem of providing a novel liquid repellent. A liquid repellent that contains a poly(hydrocarbylamine) derivative that is a poly(hydrocarbylamine) that has been substituted with one or more substituents, at least one of said substituents being on the amine nitrogen of the poly(hydrocarbylamine) and being represented by the formula -Ray [in which Ray representsa hydroxyethyl group that may have one or more substituents (at least one of said substituents being an alkyl group that may have one or more substituents)].

Description

technical field [0001] The present invention relates to a liquid repellent and the like. Background technique [0002] Conventionally, liquid repellents using various fluorine-containing compounds excellent in oil repellency are provided. [0003] However, such fluorine-containing compounds have low solubility in general-purpose solvents (fluorine-free organic solvents), and therefore need to be dissolved in expensive fluorine-containing organic solvents at the time of coating. [0004] On the other hand, Patent Document 1 proposes an oil-repellent and / or water-repellent coating agent having high solubility in general-purpose solvents. [0005] prior art literature [0006] patent documents [0007] Patent Document 1: International Publication No. 2013 / 115380 Pamphlet Contents of the invention [0008] The technical problem to be solved by the invention [0009] It would be useful to provide a liquid repellent that can suppress the use of expensive fluorinated solvent...
