Abstract: Structured adhesive constructions are provided. The adhesive constructions comprise a layer of a first adhesive with a first property and a layer of a second adhesive with a second property. The layer of the first adhesive comprises a plurality of spaced apart stripes of adhesive, coated on or laminated to a facestock or release liner. The layer of the second adhesive comprises a plurality of spaced apart stripes of adhesive, coated on or laminated to the facestock or release liner and located between the plurality of stripes of the first adhesive. The use of two different adhesives enables manipulation of desired adhesive properties in a single adhesive construction. The resulting adhesive may have two or more different desired properties, such as adherence at both high and low temperatures, or initial repositionability followed by permanent adhesion, or other combinations of desired properties. A coating die and a method of coating structured adhesive constructions are also provided.

Abstract: This invention relates to antimicrobial composites, films, labelstocks and labels. The antimicrobial composites comprise a mixture of (A) a terpolymer prepared from a mixture comprising (i) an olefin, (ii) at least one copolymerizable comonomer comprising ethylenically unsaturated organic acids or esters, vinyl esters of saturated carboxylic acids and mixtures of two or more thereof, and (iii) carbon monoxide, and (B) an antimicrobial composition which comprises at least one metal chlorite and at least one hydrophilic material capable of reacting with the metal chlorite when exposed to water. The composites which are described herein are useful in preparing films, labelstocks and labels which exhibit the desirable antimicrobial properties by providing a controlled release of chlorine dioxide gas over an extended period of time.

Abstract: A transdermal drug delivery device involving a macromonomer-containing acrylate or methacrylate copolymer, a softener, and a drug. Also a pressure sensitive skin adhesive involving a macromonomer containing acrylate or methacrylate copolymer and a softener.

Abstract: Disclosed is a breaking head mounted to an excavator for removing rocks on or in the ground at construction work. The breaking head includes lateral plates positioned between an upper plate and a lower plate, and a rotary plate connected to a rotary shaft installed to an upper end of the upper plate. The rotary plate has brackets to be engaged to a link and an arm of the excavator. The breaking head further includes a plurality of pivot cylinders at a rear portion of the breaking head for pivoting the breaking head left and right around the rotary shaft and inclined bearing members attached between a plurality of bearing members installed along four corners of the lower plate.

Abstract: This invention relates to an aqueous film-forming mixture which does not contain a vinyl halide and which can be utilized to prepare conformable films which are useful in various applications such as adhesive tapes, labels and decorative sheets. The aqueous film-forming mixtures generally comprise, based on the weight of the solids in the aqueous mixture, (A) from about 50% to about 80% by weight of an acrylic-urethane copolymer which forms a film having an elongation at break of at least about 300%, and (B) from about 5% to about 25% by weight of an acrylic polymer or copolymer having a Tg of less than about 55° C., wherein the acrylic polymer or copolymer (B) is different from the acrylic-urethane copolymer (A). The aqueous mixtures also may contain up to about 40% by weight of a pigment.

The composites which are described herein are useful in preparing films, labelstocks and labels which exhibit the desirable antimicrobial properties by providing a controlled release of chlorine dioxide gas over an extended period of time.

Abstract: This invention relates to antimicrobial composites, films, labelstocks and labels. The antimicrobial composites comprise (A) a polymer mixture comprising a mixture of at least one styrene polymer and at least one urethane polymer, and (B) an antimicrobial composition which comprises at least one metal chlorite and at least one hydrophilic material capable of reacting with the metal chlorite when exposed to water. The composites which are described herein are useful in preparing films, labelstocks and labels which exhibit the desirable antimicrobial properties by providing a controlled release of chlorine dioxide gas over an extended period of time.
