ABSTRACT:
The invention relates to a process of producing a surface hardened woody decorative sheet by reacting a cellulose material such as a wood flour, a wood chip, a chaff, etc., with a dibasic acid anhydride and a monoepoxy compound having a polymerizable double bond to form a setting composition mainly composed of an oligoesterified cellulose material having a polymerizable double bond and an oligomer having a polymerizable double bond, placing in layer the setting composition on a woody sheet, and hot-pressing them to integrate the setting composition and the woody sheet in a body.
