Abstract
Abstract A recording medium with a multicolor high resolution pattern created by layer packs. Pattern-forming layers of the layer packs are successively applied by photolithographic means in a sequence corresponding to a color of the high resolution pattern. The pattern-forming layers of the layer packs are separate from one another on the substrate of the recording medium. The process for producing the recording medium includes applying a photoresist layer to a substrate and developing the photoresist. Pattern-forming layers are successively applied over the whole surface of the substrate in a sequence corresponding to a color. The remaining photoresist and the layers overlying it are removed to leave a sequence of pattern-forming layers on the substrate separate from any adjacent pattern-forming layers.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
148 words
In a recording medium for a multicolor high resolution pattern, said medium having a substrate which supports at least two pattern-forming layer packs, each comprising a filter such that each layer pack defines a respective color, the improvement comprising: at least one of said layer packs comprising at least an interference filter having a pattern forming interference layer patterned in the pattern of the interference filter of the respective one of the layer packs, said pattern forming interference layer extending over only a part of the substrate, only in a region defined by the pattern of the interference filter; at least the pattern forming layers of a first filter included in a first one of the layer packs being applied to the substrate locally separated from and prior in time to the pattern forming layers of a second filter included in a second one of the layer packs.
Claim 2
Dependent Claim
148 words
In a recording medium for a multicolor high resolution pattern, said medium having a substrate which supports at least two pattern-forming layer packs, each comprising a filter such that each layer pack defines a respective color, the improvement comprising: at least one of said layer packs comprising at least an interference filter having a pattern forming interference layer patterned in the pattern of the interference filter of the respective one of the layer packs, said pattern forming interference layer extending over only a part of the substrate, only in a region defined by the pattern of the interference filter; at least the pattern forming layers of a first filter included in a first one of the layer packs being applied to the substrate locally separated from and prior in time to the pattern forming layers of a second filter included in a second one of the layer packs.
