Abstract
The present invention makes available a paper product with a silicone oil-repellent, activatable adhesive coating that can be printed with a laser printer, with the adhesive coating serving to seal a single sheet to itself or neighboring sheets of paper products to one another, and with the silicone-oil repellency being obtained by means of a material selected from the group of fluoroalkyl sodium sulfate(s), fluoroalkyl polyoxyethylene polymer(s), polyvinyl alcohol(s) and mixtures thereof.
Claims16
A paper product with a silicone oil-repellent, activatable adhesive coating that can be printed with a laser printer, with the adhesive coating serving to seal a single sheet to itself or neighboring sheets of paper products to one another, characterized in that the silicone oil repellency is obtained with the use of a substance selected from the group of fluoroalkyl sodium sulfate(s), fluoroalkyl polyoxyethylene polymer(s), polyvinyl alcohol(s) and mixtures thereof.
The paper product as in any one of the preceding claims, characterized in that the adhesive coating comprises a remoistening adhesive that can be activated with water.
The paper product as in any one of the preceding claims, characterized in that the adhesive coating comprises a pressure-activated self-sealing adhesive.
The paper product as in any one of the preceding claims, characterized in that the adhesive coating is applied to defined areas.
The paper product as in any one of the preceding claims, characterized in that the constituents of the adhesive coating are fine-tuned to ensure that during the coating procedure, a rapid-phase separation takes place, with the silicone oil-repellent substances essentially remaining on the surface of a coated substrate.
The paper product as in any one of the preceding claims, characterized in that the adhesive is applied in an amount of 2-15 g/m2.
The paper product as in any one of the preceding claims for use as a pressure-seal mailer.
