Description

[Technical Field]

[0001] The present disclosure relates to a curable composition comprising a fluorine-containing compound. [Background technology]

[0004] The fluoropolyether group-containing acrylic compound described in Patent Document 1 cures when exposed to ultraviolet light, but in places where ultraviolet light is difficult to irradiate, it may not cure sufficiently, resulting in uncured areas. Furthermore, the resulting cured product has a low modulus of elasticity and poor elongation. The fluoropolyether group-containing silane compound described in Patent Document 2 can be cured by moisture (water), but the curing speed is slow, and the liquid may spread and drip when applied.

[0008] As used herein, the term "monovalent organic group" refers to a monovalent group containing carbon. The monovalent organic group is not particularly limited, but may be a hydrocarbon group or a derivative thereof. A hydrocarbon group derivative refers to a group having one or more N, O, S, Si, amide, sulfonyl, siloxane, carbonyl, carbonyloxy, etc. at the end or in the molecular chain of the hydrocarbon group. Note that when simply referring to an "organic group," it refers to a monovalent organic group. Furthermore, the term "divalent organic group" refers to a divalent group containing carbon. Examples of such divalent organic groups include divalent groups in which one additional hydrogen atom has been eliminated from an organic group. Similarly, a trivalent or higher organic group refers to a group in which a predetermined number of hydrogen atoms have been eliminated from an organic group.

[0009] As used herein, the term "hydrocarbon group" refers to a group containing carbon and hydrogen, which is obtained by removing a hydrogen atom from a hydrocarbon. Such hydrocarbon groups include, but are not limited to, C 1-20 Examples of hydrocarbon groups include aliphatic hydrocarbon groups and aromatic hydrocarbon groups. The "aliphatic hydrocarbon group" may be linear, branched, or cyclic, and may be saturated or unsaturated. The hydrocarbon group may contain one or more ring structures. The hydrocarbon group may be substituted with one or more substituents.

[0010] As used herein, the substituent of the "hydrocarbon group" is not particularly limited, but examples thereof include a halogen atom, a C 1-6 Alkyl group, C 2-6 Alkenyl group, C 2-6 Alkynyl group, C 3-10 Cycloalkyl groups, C 3-10 Unsaturated cycloalkyl groups, 5-10 membered heterocyclyl groups, 5-10 membered unsaturated heterocyclyl groups, C 6-10 Examples include one or more groups selected from aryl groups and 5- to 10-membered heteroaryl groups.

[0011] As used herein, the term "hydrolyzable group" refers to a group that can undergo a hydrolysis reaction, i.e., a group that can be removed from the main skeleton of a compound by a hydrolysis reaction. Examples of hydrolyzable groups include -OR j , -OCOR j , -ON=CR j 2, -NR j 2, -NHR j , —NCO, —NCO, or halogen (wherein R j is a substituted or unsubstituted C 1-4 (representing an alkyl group) and the like.
