Abstract: An authenticity discriminable printed matter in which a latent image cannot be visually identified under ordinary visible light but appears upon being irradiated with UV rays. A basic image is formed on a base material. The basic image is made of a latent image portion and latent image peripheral portion. The latent image portion and latent image peripheral portion cannot be visually discriminated, and each of them is formed from a set of dots continuously laid out at a predetermined period. The resolution of the dots of the latent image portion is different from that of the dots of the latent image peripheral portion. The latent image portion and latent image peripheral portion have the same percent dot area per unit area and different dot peripheral lengths (contour lengths) per unit area. The latent image portion and latent image peripheral portion are printed by color fluorescent ink, thus obtaining printed matter.

Abstract: A process for producing a tubular laminate which comprises, discharge-treating an outer surface of a tubular fluorine-containing resin molded article in an inert gas atmosphere containing an organic compound having a functional group, extruding a molten resin onto the treated surface and coating the treated surface with the molten resin. According to this process, there can be obtained a strong adhesion between the fluorine-containing resin molded article and the coating resin without using an adhesive. Therefore, an applying step of the adhesive can be omitted and the tubular laminate can be produced continuously.
