Abstract

PURPOSE:To make a quantity suitable for a little amount of use without causing irregular color, uneven dryness, etc., by a method wherein an adherend for cosmetic material is dipped in a slurry material and the slurry material is equally attached in form of a thin film on its surface. CONSTITUTION:An adherend 3 for cosmetic material is stuck by an adhesive 4 on a separating paper pattern 6. On the other hand, a base 5A of powdered cosmetic material with a specified quantity is filled in a wide mounted vessel 7 and the slurry material 5B is made by adding a volatile solvent A with a specified quantity. When the adherend 3 for cosmetic material stuck on the separating paper pattern 6 is pulled up after being dipped in the slurry material 5B for 1 to 2 seconds, a slurry thin-film layer 5C is formed with both surface tension and adhesive power on its surface. After infrared rays are irradiated from infrared lamps 8, 8 on the layer and the volatile solvent A is evaporated, the slurry thin-film layer 5C forms a solid thin-film layer 5 which is equally solidified on the outer surface of the adherend 3 for cosmetic material. After the adherend 3 for cosmetic material is torn off from the separating paper pattern 6, it is stuck by the adhesive 4 on the surface of a ground paper part 2A of the ground paper 2.
