You may mix | blend 1 type, or 2 or more types of the lower alcohol of 5 thru | or 5. The viscosity of the oil (including alcohol) ranges from low to high, but it is an essential requirement of the present invention that the viscosity of the oil phase constituted by the oil is 500 cps or less at 25 ° C. The high-viscosity oil component may be blended as long as the viscosity of the entire oil phase is within the range of 500 cps or less at 25 ° C. Similarly, the viscosity of the oil phase blended with the above-mentioned resin soluble in oil is 500 cps at 25 ° C.
The following is possible. Examples of the resin referred to herein include general oil-soluble resins, for example, aromatic hydrocarbon resins (Nisseki Neopolymer T, 12 manufactured by Nippon Oil Co., Ltd.).
