PURPOSE:To obtain the subject gold or silver thread improved in gloss and feeling, by providing a silver vacuum deposition layer through an undercoating layer on one surface of each polyester film, a finish coating layer thereon and a fluororesin and polyolefin layers on the other surface and laminating the resultant filmy materials. CONSTITUTION:The objective gold or silver yarn thread by vacuum depositing silver through an undercoating layer 2 consisting of an acrylic melamine resin based coating, etc., on one surface of each polyester film 1, such as polyethylene terephthalate film, to form a silver vacuum deposition layer 3, applying a finish coating thereon to form a finish coating layer 4, on the other hand, forming a fluororesin layer 5 and/or polyolefin resin layer 5 using tetrafluoroethylene resin, etc., on the other surface of the above-mentioned film 1 to provide sheets of filmy materials 10 and subsequently laminating two sheets of the resultant filmy materials 10 with the afore-mentioned finish coating layers 4 inside. |
