PRESSURE−SENSITIVE ADHESIVE FOR THE SKIN AND TAPES OR SHEETS FOR THE SKIN MADE BY USING THE SAME

摘要

The invention provides a pressure−sensitive adhesive for the skin excellent in pressure−sensitive adhesiveness to the human skin and repeelability therefrom,which does not cause the horny layer to be torn away in peeling and is lowly irritant to the skin;and tapes or sheets made by using the same.The pressure−sensitive adhesive is characterized by comprising(a)100 parts by weight of a copolymer which is prepared from an olefinic macromonomer and a vinyl monomer and whose molecular weight(in terms of polystyrene and as determined by gel permeation chromatography(GPC))has a two−peak distribution(with the proviso that when the copolymer is to be post−cured,the distribution is one as determined before the post cure)and(b)20 to 250 parts by weight of a softener which is compatible with the copolymer and liquid or pasty at room temperature and has a boiling point of 250°C or above(with the proviso that when the content of the softener(b)exceeds 80 parts by weight,the copolymer must be post−cured).
