Description

technical field

[0001] The present invention relates to a curable composition cured by irradiating active energy rays such as ultraviolet rays and electron beams, and a cured product thereof. Background technique

[0002] Although thermosetting and solvent-volatile resin compositions are sometimes used for coating films, there are problems that thermosetting resin compositions are not suitable for substrates without heat resistance, and solvent-volatile resin compositions have a large load on the environment. .

[0003] In addition, in recent years, as a protective coating material for preventing scratches and contamination on the surface of various substrates, as well as adhesives and sealants for various substrates, it is required to be able to form hardness, softness, etc. on the surface of various substrates. A curable composition of a cured film excellent in durability, scratch resistance, abrasion resistance, low warpage (the cured film obtained by curing the curable ...
