Abstract: The present invention relates to a coating material containing a resin component and at least one kind of oil component P, in which the oil component P can exude out from a cured or dried coating film layer to which the coating material has been applied when a temperature drops to a predetermined value or less, a wetting parameter is 0.5 (J/cm3)1/2 or less, and a gel fraction of the coating film layer is 30% or more.

Abstract: The purpose of the present invention is to provide a product, in particular, a coating material capable of preventing icing and/or snow accretion. This product includes a first oil component, a second oil component, and a first resin precursor, which is a precursor for a resin component. The first resin precursor including the first and second oil components is cured to form an oil-containing resin layer including the first and second oil components and the resin component. The second oil component constitutes a low-temperature phase-separable oil component that may be phase-separated from the first oil component to exude from the oil-containing resin layer when a temperature decreases to a predetermined value or lower.

Abstract: The purpose of the present invention is to provide a sheet body having an improved function of preventing icing and/or snow accretion. At least included are a solid oil-containing resin layer containing an oil and an oil-permeable surface resin layer that has higher wear resistance than the oil-containing resin layer and is layered on one of surfaces of the oil-containing resin layer. The oil included in the oil-containing resin layer includes a low-temperature exuding oil component capable of exuding from the oil-containing resin layer when a temperature decreases to a predetermined value or lower, and the surface resin layer has enough oil permeability to permeate the low-temperature exuding oil component exuding from the oil-containing resin layer to a surface of the surface resin layer that is opposite to a side of the oil-containing resin layer.
