Description of the Related Art There is a veneer-attached veneer in which a thinly-cut veneer is adhered to the surface of a plywood, which is widely used for furniture, floor materials, wall materials and the like. However, the veneer adhered to the surface of the veneer or veneer expands and contracts due to changes in ambient temperature and humidity, and thus has a problem in that cracks occur on the surface of the veneer. This is considered to be largely due to the movement of the fibers of the veneer on the plywood surface of the substrate.

The effect on the veneer that is made and adhered to the surface can be minimized, and the occurrence of cracks in the veneer can be reduced. Further, by adding an adhesive to the treating agent, the plywood and the veneer are more firmly bonded to each other, and the peeling resistance is improved.
