Described herein is a composition comprising a partially fluorinated compound selected from the group consisting of: (a) I(CF)CHCFI; (b) ICFCH(CF)CHCFI; (c) I(CF)CH&#x2550;CF; (d) CF&#x2550;CH(CF)CHCFI; and (e) CF&#x2550;CH(CF)CH&#x2550;CFwherein x is an odd integer selected from 3 to 11, and y is an integer greater than 2, along with methods of making and polymerizing such compounds.

Partially fluorinated compounds

A vinyl graphic marking film or label coated with a pressure sensitive acrylic adhesive designed to achieve high or permanent adhesion to polymeric low energy surfaces is disclosed. In addition to good adhesion to low energy surfaces, the graphic marking film or label may have microperforated or micro-rough edges which initiate tearing when removal is attempted. The article maintains flexibility and film strength for easy fabrication in graphic marking film or label manufacture.

Pressure sensitive adhesives for use on low energy surfaces

The present invention relates to graphic or informational articles that may be applied to a surface of a translucent or substantially clear substrate so that the image may be viewed through the substrate. The present invention is an indoor advertising system or kit that includes two components. The first component is a substantially clear, perforated imageable film layer with a perforated adhesive layer on a surface thereof. The second component is a non-perforated colorant transfer component that includes a removable carrier film with at least one color layer on a surface thereof. The present invention further includes a process for making the graphic articles. In the process of the present invention, an image layer is formed on a first major surface of a substantially clear, perforated imageable film layer. A colorant transfer component with at least one colored layer comprising a pigment is laminated to the imageable film layer such that the at least one colored layer is adhered to the unperforated areas of the image layer. The colorant adheres to the unperforated land areas of the image layer without significant bridging across the apertures of the image layer.

Method for making unidirectional graphic article

Acrylate copolymer pressure sensitive adhesives (PSAs) which incorporate relatively small amounts of a plasticizer are disclosed. The resulting PSAs exhibit improved low temperature performance and minimal effect on other properties, when used as adhesives for graphic marking films. The adhesive system has been found to allow the graphic marking film to be applied at temperatures as low as 20.degree. F. (-7.degree. C.) and to improve the ability of the film to be applied to a substrate without trapping air between the marking film and the substrate. The adhesive system of the marking film also demonstrates resistance to tenting around the compound curved surfaces of rivet heads and corrugations typical of truck trailer sides.

Water-based pigmented inks

A method and apparatus to improve toner drying on electrostatic printing media is disclosed. A drying apparatus placed between two print stations in a single pass electrostatic printer provides air from two different drying assemblies, one adjacent to one print station and a second adjacent to a second print station.

Method and apparatus to dry media during electrostatic printing

An adhesive sheet having an adhesive layer and at least one surface being topologically microstructured, either with configured structures or a coating of particles and an underlying adhesive such that the adhesive layer has at least two levels of adhesion, a contact bond and an application bond, such that initial contact bond is substantially less than the application bond and that the contact bond simultaneously changes to the application bond with the application of pressure onto the adhesive sheet.

Positionable and repositionable adhesive article

Method of preparing an adhesive sheet comprising (1) a backing, and (2) an adhesive layer having at least one topologically microstructured surface comprising a plurality of pegs, optionally containing one or more beads, substantially uniformly distributed and protruding outwardly from the adhesive layer, wherein the pegs have essentially flat tops that comprise less than 25% of the total surface contact area of the adhesive layer, and have a height of at least 15 .mu.m.
