摘要:
The present invention relates an adhesive patch comprising a backing layer and an adhesive layer that contains a drug, wherein the adhesive layer contains a mixed adhesive base containing a hydrocarbon rubber and a silicon-containing polymer. The adhesive patch of the invention shows extremely superior skin absorbability of a drug in a preparation, reduced skin irritation, and excellent aging stability of the drug in the preparation, and can achieve easiness of drug-taking methods and improvement in compliance.
摘要:
The invention provides a process for production of pressure-sensitive adhesive shaped products which enables proper shaping of a tacky polymer through proper control of the rate of crosslinking thereof, specifically, a process for production of pressure-sensitive adhesive shaped products which comprises mixing a polymer bearing hydroxyl or carboxyl groups with one or more crosslinking agents selected from the group consisting of metal alcoholates and boron compounds in the presence of a lower alcohol and then subjecting the obtained mixture to shaping either accompanied with or followed by thermal crosslinking.
摘要:
The present invention is a pressure sensitive adhesive comprising: an ingredient (A) which is a copolymer of a carboxyl group-containing monomer and (meth)acrylic ester; and an ingredient (B) which is a copolymer of a pyrrolidone group-containing monomer and (meth)acrylic ester, wherein the ingredient (A) is crosslinked by at least one crosslinking agent selected from the group consisting of a metal chelate compound, a metal oxide and a metal hydroxide, and the blending ratio of the ingredient (A) is 70 to 90 weight % based on the total amount of the ingredient (A) and ingredient (B).
摘要:
An adhesive which comprises aqueous and nonaqueous polymers suitable for holding an lipophilic drug, etc., and has tackiness and cohesiveness which are sufficient for the plaster of a patch; and a patch employing the adhesive. The adhesive contains a polymer which comprises one or more kinds of acrylic or methacrylic monomer units, at least one kind of the monomer units having a hydroxy group, and which has been crosslinked with a boron compound.

A pressure-sensitive adhesive base which contains the liquid organic ingredient and which, despite this, has moderate pressure-sensitive adhesion properties (tackiness and cohesive force) and causes no bleeding. It hardly injures the keratin of the skin and is inhibited from irritating the skin. The pressure-sensitive adhesive base comprises the following ingredients (A) to (C): (A) a copolymer comprising units of a monomer containing a carboxy group and units of a (meth) acrylic ester; (B) one or more, liquid or semisolid organic compounds which are compatible with the copolymer of the ingredient (A); and (C) at least one member selected among polyvalent-metal oxides and polyvalent-metal hydroxides, the total content of the ingredient (C) being 0.001-5 mass % based on the whole pressure-sensitive adhesive base. The adhesive base contains substantially no water.

摘要:
For folding an annular resilient band about a circumferential fold line, the band is first wrapped on a generally cylindrical, radially collapsible drum structure having a cylindrical external contour about the center axis of the drum and an annular zone radially inward of the contour with an inflatable annular first bladder positioned in such a manner as to have a folded-over axial end portion axially protruding into the aforesaid annular zone and with an inflatable annular second bladder positioned radially inwardly of the first bladder and in such a manner that the first and second bladders have axial portions overlapping each other, whereupon the first bladder is inflated to a medium expanded state so that an axial end portion of the band on the drum structure is contacted by the bladder and displaced radially outwardly and thereafter the first bladder is moved axially away from the drum structure for forming an annular gap between the first bladder and the axial end portion of the band, the second bladder being thereafter inflated to a fully expanded state for deforming the first bladder axially between the band and the second bladder so that the axial end portion of the band is caused to further turn about the aforesaid fold line until the axial end portion of the band is received on an adjacent axial portion of the band.
