  • Patent number: 5306746
    Abstract: The present invention relates to a resin composition which selectively absorbs light of the wavelength band in the vicinity of wavelength 580 nm, as well as to the optical products to be formed from this resin composition. The beads possessing light selective function are formed from a transparent polymer which contains a neodymium compound: these beads are then dispersed in a transparent resin composition. Comparing to the case when the neodymium compound is directly dispersed in the resin composition, a large amount of neodymium compound can be added to the resin composition without decreasing the mechanical and thermal properties of the resin composition.

As compared to prior tapes the novel tapes have equal or better adhesive performance, i.e., at least 35 N/dm of peel adhesion, with a faster drying adhesive layer. The tapes can, therefore, be produced more economically. Furthermore, the adhesive bubbling problem formerly seen with paper backings is eliminated.
