THIS INVENTION FOCUSED ON PREPARATION OF HIGH PERFORMANCE COLORED PAPER, CHARACTERIZED BY HIGH STRENGTH, THERMAL RESISTANCE, FIRE RETARDANCE, BIOLOGICAL RESISTANCE, MAGNETIC PROPERTIES, AS WELL AS ITS DURABILITY TOWARD AGEING. IN THIS RESPECT CARBOXYMETHYL CELLULOSE-COPPER(II) COMPLEX WAS USED AS PAPER ADDITIVE. DIFFERENT COPPER SALTS (E.G., CHLORIDE, SULFATE AND ACETATE) AS A SOURCE OF COPPER IONS IN COMPLEX, AS WELL AS PH- VALUE DURING SHEET FORMATION WERE EXAMINED. IT WAS FOUND THAT, THE BEST POLYMER COMPLEX WHICH ACHIEVED HIGH PAPER QUALITY IS THAT PRODUCED FROM USING COPPER SULFATE AS THE ORIGIN OF COPPER ION, AT PH ~6.0. ALSO, BY THIS APPROACH THERE IS NO ANY POLLUTION PROBLEM RESULT FROM DISPOSAL THE WATER OF PAPER MACHINE
