Title:

PRESSURE SENSITIVE ADHESIVE TAPE AND METHOD OF LENS SHAPE MACHINING

Document Type and Number:

WIPO Patent Application WO/2004/067227

Kind Code:

A1

Abstract:

A pressure sensitive adhesive tape to be disposed between a lens and at least one of a pair of chucks fitted to a lapping machine, which pressure sensitive adhesive tape has an adhesive surface to be brought into contact with the lens that exhibits an adhesive strength of 4 gf (0.0392 N) or greater as measured in accordance with the method of adhesive strength testing through 180° peeling specified in JIS Z 0237 “method of testing pressure sensitive adhesive tape or pressure sensitive adhesive sheet”, in which a polyethylene terephthalate plate having been surface treated with a fluorinated silicone release agent is used as the test plate. Thus, there is provided a technique of shape machining of a lens provided with an antifouling layer of fluorinated silane compound excelling in antifouling effects.
