Abstract: Radiation curable coating compositions for providing solvent-resistant abhesive coatings comprise polyfluorinated acrylates and methacrylates, polyethylenically unsaturated crosslinking agents and a film-forming organic polymer. The compositions can be used after radiation curing to render substrates oil, soil, and water repellent.

Abstract: A disposable diaper can be almost completely degradable when each of its diaper closure tapes has as its backing a polyolefin film containing a chemical prodegradant such as a metal salt together with an unsaturated elastomer such as a block copolymer of styrene and isoprene of butadiene. Preferably, the polyolefin of each of those backings is a copolymer of polypropylene and polyethylene or a blend of crystalline isotatic polypropylene and a compatible ethylene-based polymer.

Abstract: A refastenable adhesive closure is provided. The closure has a pressure-sensitive adhesive-bearing fastening tab and a target portion, or target strip, having a working face for contact with the adhesive-bearing fastening tab. The working face of the target strip is formed with peaks and valleys, the height of the peaks above the valleys being substantially uniform and from about 40 to 300 .mu.m, the spacing between adjacent peaks being from about 50 to 500 .mu.m, the back face of the target portion being substantially flat, and the thickness of the adhesive layer of the tab being no more than about 90% of the height of the peaks above the valleys. The closure is resistant to contamination by dust and other fine particulate matter and is especially useful for refastenable disposable diaper closures and refastenable envelope closures.

Abstract: A cleaning device for removing debris from the tape of a reel to reel magnetic data tape cartridge includes a cleaning material mounted adjacent the tape path to constantly contact and remove debris from the tape. Preferably, the cleaning material both wipes debris from the tape and retains the debris.

An alternate emebodiment which permits both sides of the magnetic tape to be cleaned includes mounting the cleaning material on a arm which is pivotably mounted to the cartridge. The arm pivots to maintain contact with the tape and is shaped to provide a plurality of contact portions between the cleaning material and the tape.

Abstract: Disposable adherent collars based on low cost supple sheets carrying a low-adherency pressure sensitive adhesive are disclosed. The adherent collars of the present invention are significantly more comfortable to wear than prior art adherent collars due to the suppleness of the sheet used in the collars, and to the low-adherency character of the PSA, achieved preferably through the use of a discontinuous layer of PSA material. Because of the suppleness of the sheet the low-adherency adhesive is effective to hold the sheet in place.
