Description

At present, as a raw material of a commercially available decane-based coating agent, a trifunctional decane is mainly used, and a polyfunctional siloxane having a moderate hardness and flexibility is formed by the trifunctional decane. However, the trifunctional decane film is not sufficiently hard-coating, and it is easy to compensate for this defect by mixing tetrafunctional decane or colloidal cerium oxide in trifunctional decane. However, if the film is hardened, it becomes easy. Cracking, which makes the adhesion worse. For example, a composition for forming an antifouling film containing a trifunctional alkoxydecane compound having an epoxy group is proposed as a coating agent for a decane-based coating (see, for example, Patent Document 1).

Heretofore, the present inventors have provided a method of irradiating an organic ruthenium compound with ultraviolet rays in the presence of a photosensitive compound to have a surface having a very high hardness and having an appropriate hardness on the inner and back sides, and a substrate.
