Once disclosed a kind of " transparent glass building decoration veneer " product in Chinese patent 87211062 texts, this product characteristics is that it can present different colour bar patterns with the difference of eye-observation angle, its shortcoming is that certain interval is arranged between colour bar, this at interval interior color is constant, the color of colour bar is sudden change, and can not form bigger global pattern equally.

The purpose of this utility model is to overcome the defective of prior art, and then provide a kind of rainbow decorative glasswork, these goods can form big (the multicoloured donut of φ 200～1500mm) or parallel lines strip pattern, arbitrarily angled observation on transmission and reflection direction all has the rainbow effect, and when angle of incidence of light or the variation of eye-observation angle, can be observed the whole rainbow pattern of continuous color change from it.

In order to realize the foregoing invention purpose, the technical solution that the utility model designer adopts is: the rainbow decorative glass that is provided has a transparent glass substrate or colored glass substrate, the shape of substrate is generally circle or rectangle, on a surface of substrate, be coated with (deposition) at least three layers of transparent thin film layer are arranged, the material that constitutes transparent thin film layer has two kinds at least, in the enforcement, the thickness of thin film layer is directly done regular distribution with the geometrical line of substrate surface, can then distribute along the radius of circular substrate or along the straight line wire gauge of rectangular substrate.

The utility model goods have utilized the interference of light principle, under white light, the multicoloured concentric ring-shaped or the colored global pattern of parallel lines strip that have transmission and reflection on the decorative glass simultaneously, and reflection color and the complementation of transmission color, make the people all can be observed of the variation of rainbow effect in any direction along with angle of incidence of light or eye-observation angle, the whole rainbow pattern of the utility model goods will produce the successive color change, can be observed the expansion of colored donut and the continuous rolling of contraction or colored parallel lines from it and pass through to change composition structure and the thicknesses of layers that film is, can produce the rainbow pattern of different color easily, be particularly suitable for the production of the rainbow decorative glasswork of many kinds color.Because the utility model adopts vacuum coating technology, also can coat the big area (goods that are whole circular or straight line strip pattern of φ 200～1500mm) easily.

Below with reference to accompanying drawing the utility model is done further narration
