Abstract
Abstract A composition applied as a coating to material intended to be utilized as a label for displaying pricing, and other information, as in the supermarket, the composition including a solution of approximately 70% acrylic, or an overprint varnish, a silica flatting agent included at about 3% by weight, an alcohol solvent included at approximately 17% to 18% by weight, and an ester solvent at approximately 9% to 10% by weight. In alternative coating, such as for use in conjunction with differing printers, a water base solution must be employed, and this includes a solution of a 50% water based acrylic, having added to it approximately 25% by weight of water, and 25% by weight of extending varnish. The composition is applied to the label material by gravure roll, or any other flexographic printing process, dried, and then shipped to the supermarket or its headquarters wherein the label material can be cut, and printed upon one of the laser printers with the aforementioned data, for ready application.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A data displaying label having a substantially continuous film coating applied to at least one face thereof, said film coating comprising a laser printable acrylic based pre-mixed compound of select proportions, said compound forming the coating including approximately 50%-84% by weight of the printable acrylic, approximately 10% -25% by weight of an alcohol solvent, approximately 5-20% by weight of an ester solvent, and approximately 1%-5% by weight of a silica based flatting agent, and said film coating adhering the laser pigment ink to the coated label with an immediate bonding and fusing of the ink to the coated label during preparation of the label with the desired data, in order to provide a printed label that will not smudge, scratch or fade.
Claim 2
Dependent Claim
122 words
A data displaying label having a substantially continuous film coating applied to at least one face thereof, said film coating comprising a laser printable acrylic based pre-mixed compound of select proportions, said compound forming the coating including approximately 50%-84% by weight of the printable acrylic, approximately 10% -25% by weight of an alcohol solvent, approximately 5-20% by weight of an ester solvent, and approximately 1%-5% by weight of a silica based flatting agent, and said film coating adhering the laser pigment ink to the coated label with an immediate bonding and fusing of the ink to the coated label during preparation of the label with the desired data, in order to provide a printed label that will not smudge, scratch or fade.
