A release coating that exhibits superior release properties includes about 70% Goldschmidt RC 711 silicone, about 30% Goldschmidt RC 726 silicone and about 3% of total silicone weight photo initiator. The silicone mixture provides a smooth release and better avoids the deleterious effects of aging such as yellowing and flaking. In addition, the silicone mixture is a soft silicone such that it will not come off in a printer. The invention also includes a method of making a release coating and a method of applying a release coating to a substrate.

Release coating for linerless labels, method of making a release coating and method of applying a release coating

A silicone release composition having a non-gloss, i.e., matte finished, surface and a linerless label incorporating the silicone release composition. The release composition includes a crosslinked silicone-based polymer having microparticles of a polymeric wax at least partially embedded therein. The polymeric wax may be polytetrafluoroethylene, polypropylene or other polyolefin, or a hydrocarbon-based wax. The microparticles of polymeric wax cause incidental light to scatter upon reflection, giving the release composition surface matte appearance. This makes the release composition particularly useful for linerless labels on which bar coded information will be printed. Also, a method for producing linerless label stock. The method includes mixing an uncured silicone material with microparticles of a polymeric wax. The mixture is coated onto a substrate and exposed to UV radiation to cure or crosslink the silicone around the microparticles of wax. An adhesive is coated onto the side of the substrate opposite the silicone release composition and the coated substrate is wound into a roll of linerless label stock.

Matte finished release composition and linerless labels incorporating the release composition

An apparatus and method provide for the alternate manufacture of permanent adhesive or repositional linerless labels utilizing the same equipment. Indicia is applied such as by using an intelligent imaging system by at least one print station. With repositional labels, a tie coat is applied and dried, whereas with permanent labels a barrier coating is applied. Coating stations apply a repositional adhesive and release coat in the construction of repositional adhesive labels. The coating station is followed by a dryer and chill rolls. In the construction of permanent adhesive labels a coating station for applying a release coat and a release coat curing station, as well as permanent adhesive application station, are also provided. Changeover time from the manufacture of one type of label to the other is short.

Linerless label stock is produced from a single substrate utilizing a coating machine by moving the substrate through the coating machine and applying a tie coating to the substrate first face, a release coating to the substrate second face, and a pressure sensitive adhesive to the tie coating. The release coating comprises a mixture of (a) about 55 to about 95 parts by weight of a first acrylated polysiloxane having the formula I: ##STR1## wherein R is a C.sub.4 -C.sub.2 alkyl group, m is about 40 and n ranges from about 8 to about 12;

Method and apparatus for manufacturing linerless labels

A business form is particularly useful to provide labels applied to appliances, as well as appliance registration information on a paper substrate associated with the labels. A common substrate mounts a repositional adhesive label and a permanent (piggyback) adhesive label while at the same time providing appliance registration information. The substrate and the labels may be variable imaged at the same time, as with a common appliance ID number. The removable adhesive label preferably has indicia indicating appliance energy costs, while the permanent adhesive label (of paper, plastic film or metal foil) takes the place of a typically metal appliance ID tag. A release material is preferably spot coated on the top surface of the substrate, and the repositional adhesive label is applied over the release material spot coat.

Form/label combination

A pressure sensitive label form construction suitable for processing through a laser printer includes a base sheet having length and width dimensions and an upper surface coated with a release composition; and a label face sheet removably adhesively secured to the upper surface of the base sheet. The label face sheet is die cut into a plurality of individual labels and has an adhesive applied to a lower surface thereof, and a toner-receptive coating applied to an upper surface thereof. The label sheet has a width dimension less than the width dimension of the base sheet so as to avoid adhesive contamination of the printer.
