Abstract

A surface coating material is provided for forming a hydrophilic oil repellent layer on at least a part of the surface of a substrate, and the surface coating material includes one or more fluorine-based compounds represented by the following formulas (1) to (4), a binder, and a solvent.

First claim

1 . A surface coating material which forms a hydrophilic oil repellent layer on at least a part of the surface of a substrate, comprising:
one or more fluorine-based compounds represented by the following formulas (1) to (4); a binder; and a solvent.

(wherein in the above formulas (1) and (2), Rf 1 and Rf 2 each represents a linear or branched perfluoroalkyl group having 1 to 6 carbon atoms, which are the same as or different from each other, and Rf 3 represents a linear or branched perfluoroalkylene group having 1 to 6 carbon atoms;
in the above formulas (3) and (4), Rf 4 , Rf 5 , and Rf 6 each represents a linear or branched perfluoroalkylene group having 1 to 6 carbon atoms, which are the same as or different from each other, and Z includes any one of an oxygen atom, a nitrogen atom, a CF 2 group, and a CF group;
in the above formulas (2) and (4), R represents a linking group which is a divalent organic group; and
in the above formulas (1) to (4), X represents any one hydrophilicity imparting group selected from the group consisting of anion type hydrophilicity imparting groups, cation type hydrophilicity imparting groups, and amphoteric type hydrophilicity imparting groups.)

2 . The surface coating material according to claim 1 ,
wherein the mass composition ratio between the fluorine-based compound and the solvent is within a range of 0.05 to 50:99.95 to 50.

3 . The surface coating material according to claim 1 ,
wherein the binder includes any one of a resin, and water glass.

4 . The surface coating material according to claim 1 ,
wherein the mass composition ratio between the fluorine-based compound and the binder is within a range of 0.2 to 99.9:99.8 to 0.1.

5 . The surface coating material according to claim 1 ,
wherein the solvent is water, an organic solvent, or a mixture of water and an organic solvent.

6 . A coating film, comprising:
one or more fluorine-based compounds represented by the formulas (1) to (4) in claim 1 ; and a binder.

7 . A hydrophilic oil repellent member, comprising:
a substrate; and a hydrophilic oil repellent layer provided on a part or all of the surface of the substrate, wherein the hydrophilic oil repellent layer includes one or more fluorine-based compounds represented by the formulas (1) to (4) in claim 1 .

8 . The hydrophilic oil repellent member according to claim 7 ,
wherein the hydrophilic oil repellent layer further includes a binder.

9 . The hydrophilic oil repellent member according to claim 7 ,
wherein the substrate is any one or a combination of two or more selected from the group consisting of glass, plastic, metal, ceramics, stainless steel, aluminum, wood, stone, cement, concrete, fiber, cloth, paper, and leather.

10 . The hydrophilic oil repellent member according to claim 7 ,
wherein the substrate is a PET film or a glass plate.

11 . The hydrophilic oil repellent member according to claim 10 ,
wherein the total light transmittance is 90% or greater.

12 . The hydrophilic oil repellent member according to claim 8 ,
wherein the binder is an organic binder or an inorganic binder.

13 . The hydrophilic oil repellent member according to claim 7 ,
wherein a static contact angle for water on the surface of the substrate provided with a hydrophilic oil repellent layer is 15° or less, and a static contact angle for hexadecane is 65° or greater.

14 . The hydrophilic oil repellent member according to claim 7 ,
wherein the substrate is a kitchen utensil used in a kitchen or a sanitary utensil used in a sanitary facility.

15 . The hydrophilic oil repellent member according to claim 7 ,
wherein the substrate is an oil contamination protection tool for preventing sticking of oils.

16 . The surface coating material according to claim 3 , wherein the resin is a water soluble resin.
