Abstract: The present invention relates to the present invention relates to a time indicating label comprising (a) a label substrate having a first and second surface, (b) an acid-base indicator composition, and (c) an activator composition, wherein one of (b) or (c) are on the first surface of the substrate and wherein (b) and (c) when brought in contact remain adhered. The label may have a pressure sensitive adhesive on the second surface of the label. The invention further relates to a method of using the time-temperature indicating label. The labels provide an effective means for determine the safety of frozen foods. The labels also provide a means of providing security by providing name badges that are time sensitive and may not be reused. The name badges provide a means to monitor the length of a visitor's time and prevents reusing the name badge.

Abstract: An adhesive construction, characterized by excellent converting and adhesive performance, comprises a facestock, a face-side adhesive (FSA) in contact with a first surface of the facestock, and a liner-side adhesive (LSA) in contact with the FSA. The FSA is compounded with an organopolysiloxane or modified organopolysiloxane. Single layer constructions, and multilayer constructions comprising more than two adhesive layers, and unique adhesive compositions, are also provided. The constructions can be run in high-speed converting presses and adhere well to a variety of substrates.

Abstract: A cold stick pavement marking construction is provided which includes a top flexible layer and a lower adhesive layer for adhering the pavement marking construction to a pavement surface. The top layer includes thermoplastic elastomer, resin, wax and filler. The wax and resin are preferably at least partially miscible with the thermoplastic elastomer in order to prevent phase separation of the top layer. Optionally, the top layer of the pavement marking construction includes retroreflective elements for improved visibility, and skid-resistant particles for improved traction for both vehicles and pedestrians. Other ingredients in the top layer include liquid rubber, plasticizer and antioxidant.

Abstract: Three-dimensional flexible adhesive film structures are described which exhibit tack on demand characteristics. The film is capable of showing minimal or no tack under normal handling conditions, but when pressed against a target surface, exhibits the desired adhesion.

Abstract: The present invention relates to improved performance multilayer PSA constructions useful for making labels. In one embodiment the invention relates to a multilayer PSA construction comprising: (A) a multilayer adhesive laminate having an overall thickness of less than about 100 microns and comprising (I) at least one composite PSA layer comprising a continuous phase of a pressure sensitive adhesive and a discontinuous phase of non-adhesive filler particles, filler particle aggregate, or a mixture thereof, and (ii) at least one second PSA layer which is in contact with the composite layer and contains no filler or less filler than the composite layer, and (B) a facestock which is in contact with and adhered to either the composite layer or the second PSA layer of the multilayer adhesive laminate.

Abstract: The present invention is directed toward multilayer pressure-sensitive adhesive constructions with improved convertibility and aging. In one embodiment, the multilayer constructions have one layer formed of a first adhesive composition having a first glass transition temperature, and also having a tangent delta greater than about 0.5 at 102 radians per second at 20° C., and a storage modulus greater than about 3×108 dynes/cm2 at 104 radians per second at 20° C. At least a second adhesive layer is provided in the construction, the second adhesive layer comprising a second adhesive composition with a second glass transition temperature.

Abstract: An improved hot-melt pressure-sensitive adhesive (HMPSA) composition contains an elastomeric component, such as a blend of SIS and SB block copolymers, and a tackifying component comprising one or more intermediate softening point resins (ISPRs) having a ring and ball softening point of from 35 to 60° C. The improved adhesive compositions are characterized by reduced volatility, less bleed and staining tendencies, and improved overall adhesive performance. The invention also provides improved label constructions in which a release liner is coated with an HMPSA composition and laminated to a flexible facestock. Notably, even when low basis weight paper facestocks are used, the construction can be converted at high speeds.

Abstract: A method for simultaneously coating multiple thin layers of relatively viscous fluids comprises the relative adjustment of the viscosity of the fluids in order to achieve a viscosity ratio in the optimum range without adversely affecting the adhesive properties of the fluids. In the preferrred method, viscosity is adjusted by varying the temperature of one or both fluids prior to coating and/or by reformulating the liquids to vary their relative viscosities.

Abstract: The present invention is directed toward a multilayer, pressure-sensitive adhesive construction wherein one layer is formed of a first adhesive composition having a first glass transition temperature, and at least a second layer is formed of a second adhesive composition having a second glass transition temperature. The first glass transition temperature differs from the second glass transition temperature by from about 10.degree. C. to about 50.degree. C.

Abstract: The cuttability of elastomeric pressure-sensitive adhesives, particularly of hot-melt tackified mutually immiscible elastomers, is improved by the addition of surfactants containing polyethylene-oxide and polypropylene-oxide blocks.
