Abstract
The reflector of the present invention is a multi-layer reflector comprising a substrate with or without a resin layer coated thereon; a light-reflective metal layer vacuum-coated on said substrate; and a protective layer consisting of a light transmittable resin layer and a light transmittable, preferably vacuum-coated, inorganic substance layer coated on said metal layer. By this, each film can be thin as compared with each individual protective film, which leads to good heat conductivity low temperature rise, high impact strength and good durability and which gives clear reflected images or high precision light collective and light distributing properties. In addition, the coated light-reflective metal shows better regular reflectivity, giving clear and sharp reflected images and allowing more accurate light collective or light distributing properties. Furthermore, selection of an inorganic substance layer or a resin layer as the outermost protection allows the manufacture of reflectors having desired characteristics (resistance to oil, solvents, light, heat, abrasion, chemicals, water and moisture; flexibility, etc.) depending on specific requirements.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
