CONSTITUTION: This compsn. contains at least 2.5 to 20wt.% image forming compsn. comprising at least one kind of hydrolyzed polyalkoxysilane. It is supposed that when polyalkoxysilane is hydrolyzed, it produces a Si(OH)4 component.

It is specially preferable that the binder of the image forming compsn. has hydroxyl groups which enables coupling reaction of the Si(OH)4 component and the binder. Thereby, adhesion strength of the image forming compsn. to adjacent hydrophobic layers can be increased.
