An advertising sheet (1) with a latent color presentation effect is disclosed, the effect being capable of selectively exposing the latent colors to the eyes while accomplishing a shiny color presentation effect in accordance with an angle of vision. A plurality of hemispherical embossments (3), having a convex lens shape and being made of a transparent epoxy resin or an ultraviolet resin, are formed on a printed layer (2) of the sheet (1) at halftone dots formed by overlap of red, blue, yellow and black dots, thus allowing one of the latent primary colors to be selectively exposed to the eyes through the embossments (3) while shining in accordance with an angle of vision. The advertising sheet (1) thus excites customers' interest, thereby improving the advertising effect. According to the invention, a thin coated layer (4), made of a transparent epoxy resin or an ultraviolet resin, may be formed on the printed layer (2), with a plurality of wells (5) being formed on the coated layer (4) at positions around the halftone dots and individually seating an embossment (3) thereon. On the other hand, the printed layer (2) may be formed on the lower surface of a transparent plastic base sheet (6), with the embossments (3) being formed on the upper surface of the sheet (6). |
