This wax is obtained by reacting a silicone compound having a substituent with reactivity to the hydroxyl group in natural carnuba wax, with this hydroxyl group. A carboxyl group may be introduced into the molecule by reacting this hydroxyl group with a cyclic acid anhydride, and a silicone compound having a group which can react directly with this carboxyl group is made to react. Alternatively, a hydrogen silicone may be hydrosilylated by a double bond introduced by reacting an epoxy compound having a double bond with this carboxyl group.Field of SearchNatural wax containing (e.g., carnauba, montan, Japan, candelilla, etc.)Wax, bituminous or resinous material or tarry residue containing Wax containing Wax, paraffin, bituminous material, asphalt, oil shale, tar or pitch containing Organic heavy metal, aluminum, or silicon compound adjuvant Phosphorus or -C(=X), wherein X is chalcogen, attached indirectly to the silicon by nonionic bonding Carboxylic acid ester Boron, selenium, or silicon containing Silicon and the oxy of the -COO- group are bonded directly to the same hydrocarbon group Silicon is bonded directly to the oxy of the -COO- group |
