<p>PURPOSE: To obtain a special decoration effect or cat's eye effect, by forming a multi-layer resin container and charging a colored liquid therein to form a bottle. CONSTITUTION: A transparent or translucent multi-layer resin container 1 is composed of a transparent thermoplastic resin inner layer 3 and an interference layer (outer layer) 2 provided on the outer side of the inner layer 3 and made of a transparent resin selectively generating a particular color pattern due to the interference of lights. A colored liquid is charged therein. In such a bottle, reflected light or transmitted light from the colored liquid and interference colored patterns from the interference layer 2 are simultaneously visible or so-called cat's eye like decorative double-color effect can be obtained. In this time, a scale-form thin film with a high refractive index as an interference layer generating a particular color is oriented to the plane direction of the interference layer. As a scale-form thin film, mica-titanium pigment is used and the mixed ratio thereof is 2-300mg/(cm<2> per unit area converted.</p> |
