<p>A strippable, masking film useful in, for example, beautifully finishing a color boundary in two-tone coating of an automobile or the like, and a coating process using it. A coating film containing 1 to 20 parts by weight of carbon black per 100 parts by weight of a resinous component is preferable, with a coating film formed of acrylic emulsion paint and having an adhesion strength of 20 to 1000 g/inch in 180o-peeling strength being particularly preferable. The formed film can be cut by applying a YAG laser equipped with a Q switch oscillation unit in a range of 0.5 to 10 kHz in a repeating frequency of Q switch pulses, and two-tone coating can be beautifully finished utilizing it. When an adhesive paint is used as an underlying layer in contact with a substrate (prime layer) and a flexible, film-forming paint is used as surface layer (upper layer), with each layer containing carbon black described above, better effects can be obtained without damaging a substrate.</p> |
