ORNAMENTAL PLANT PRODUCTION METHOD AND ORNAMENTAL PLANT
Document Type and Number:
WIPO Patent Application WO/2024/010072
Kind Code:
A2
Abstract:
An ornamental plant production method according to the present invention comprises a drying step for drying a plant and a film formation step for forming a film of a resin composition on the surface of the dried plant. The resin composition is a coating material consisting of a prepolymer solution that is composed of a (E) polyurethane resin and has active isocyanate terminal groups, said (E) polyurethane resin being obtained by reacting a (A) polyol component and a (B) polyisocyanate component in a (D) solvent in the presence of a (C) catalyst. The (A) polyol component is a liquid carbonate polyol having two functional groups and a number average molecular weight of 2,000-3,000, and has active hydroxyl terminal groups. The (B) polyisocyanate component is an alicyclic polyisocyanate having two functional groups, and has isocyanate terminal groups. The hydroxyl equivalent (OH) of the (A) polyol component is less than the isocyanate equivalent (NCO) of the (B) polyisocyanate component. In the film formation step, a film of the (E) coating material is formed on the surface of the dried plant, and reacts with water vapor in the air to form urea bonds.
