PAPER ADDITIVE COMPOSITION CONTAINING AMIDE COMPOUND OBTAINED BY REACTING CARBOXYLIC ACID AND POLYAMINE, AND PAPER WHICH IS MANUFACTURED OUT OF THE SAME, HAVING FLEXIBILITY AND BULKINESS

摘要

PURPOSE: A paper additive composition is characterized by containing amide compound obtained by reacting carboxylic acid and polyamine. Paper manufactured out of the same is characterized by controlling foamability low in a paper making process and having bulkiness and flexibility. CONSTITUTION: A paper additive composition contains amide compound(a) obtained by reacting carboxylic acid and polyamine(formula 1: R-(NH-R1)n-NH2) or a salt of the amide compound(a). The carboxylic acid has 10-24 of number of carbons. The amide compound(a) is obtained by reacting the carboxylic acid in a ratio of 0.5-4.3mol per 1mol of the polyamine. On the amide compound, rate of tertiary amine value to a total amine value is 0.60-0.99. In the formula 1, R is H2N-R1 or R2. R1 is independently C1-C4 alkylene group. R2 is C12-C22 alkyl group or alkenyl group. n is an integer of 1-3. Paper is manufactured by adding 0.03-8pts.wt. of the paper additive composition based on 100pts.wt. of pulp.
