詳細を説明する。 The present invention meets these demands and makes it possible to display a multicolor pattern in a single cell by patterning the reflective material in the background into a multicolor pattern even if the liquid crystal used for display is monochrome. It is something. Further, the light semi-transparent reflective material according to the present invention has excellent light scattering properties for reflected light and transmitted light, has high reflectance and transmittance, and provides a clear display that is easy to see for the observer. The details of the present invention will be explained below with reference to the drawings.

In the figure, 1 is a color pattern of each color, and 2 is a white surface or a colored surface of the base. FIG. 2 is a cross-sectional view of the reflective material of the present invention, in which 3 is a light-transmitting or semi-transparent base material, 4 is a semi-transmissive and reflective resin layer according to the present invention, and 5 is a semi-transparent or semi-transmissive base material. Each color pattern has transmissive and reflective properties.

機性紫外線吸収剤を添加してもよい。 The material constituting the semi-transparent and reflective resin layer is mainly a material in which organic fluorescent pigments are dispersed in a transparent resin coating such as acrylic resin, polyester resin, epoxy resin, or polyurethane resin. In order to control the color, a colored fluorescent pigment other than white or a white fluorescent pigment colored with a dye or pigment is used. In either case, if higher fluorescence is desired, a small amount of fluorescent dye may be added at the same time. Furthermore, an appropriate amount of an organic ultraviolet absorber may be added to improve light resistance and ultraviolet resistance.

的な印刷方法が適用し得る。 The color pattern portion 5 is formed of a fluorescent pigment or a fluorescent pigment to which a dye or a pigment is added as a coloring agent, similar to the resin layer described above. Further, since a fluorescent pigment is always used in the resin layer, it is not necessary to use a fluorescent pigment in the color pattern portion, and the color pattern portion may be formed using only a dye or a pigment. Note that general printing methods such as screen printing can be applied to form the color pattern.
