Abstract
An array of color-coded papers that can be collected and recycled with white paper without separation. The sheets are individually color-coded with a printing ink including an oil-based vehicle component and a dye-free pigment component that is dispersible in a surfactant-water mix used to recycle the paper. Preferably, the color code is on a marginal area, with the image area comprising the remainder of the sheets. The invention also relates to multi-part business form sets using an array of such sheets, arranged so that each sheet is distinguishable from another sheet in the form set by the color code.
Claims12
An array of color-coded papers capable of being collected with white paper and recycled without further separation after use, said array comprising, in combination, plural individual groups of paper sheets, with each individual group comprising plural individual sheets of paper, and with each sheet in a given group being color coded such that each group is distinguishable by color from other groups in said array, and is able to be divided or classified in use by said visible color code feature, and wherein said color code of each sheet appears on at least one face of each of said sheets, in a color code area of said sheet face, said color being applied thereto using a printing ink comprising an oil-based vehicle component and a dye-free pigment component, at least said pigment component being dispersible in a water-surfactant mix used in recycling and separable from the paper fibers created by said recycling, whereby said color-coded sheets can be recycled with white paper without imparting the color from the printing ink pigment to the recycled paper.
A multi-part form comprising individual sheets of paper, said sheets including front and back faces and edges defining the outer perimeter of said sheets, wherein each sheet included in said form is distinguishable from other sheets in said form by being color-coded, said color coding being accomplished through application of a colored printing ink comprising an oil-based vehicle component and a dye-free pigment component, at least said pigment component being dispersible in a water-surfactant mix used in recycling and separable from the paper fibers created by said recycling, thus enabling all sheets in said form to be capable of being recycled as white paper without imparting the color from the printing ink pigment to the recycled paper.
A business form comprised of a plurality of individual color-coded sheets each capable of being collected with white paper and recycled as white paper without further separation by reason of the materials used to impart color coding to said paper, said form comprising plural individual sheets of paper, each of said sheets including front and back faces, outer margins, and edges defining the outer perimeter of said sheets, and wherein at least portions of said outer margin areas of said sheet faces are impressed with a colored surface-adhering printing ink to form a color code area in said margin, said printing ink comprising an oil-based vehicle component and a dye-free pigment component, at least said pigment component being dispersible in a water-surfactant mix used in recycling and separable from the paper fibers created by said recycling, said printing ink thereby enabling a visible color code to be imparted to said papers and whereby said sheets may be recycled without imparting the color from the printing ink pigment to the recycled paper.
