The invention discloses a dope for coating color tube paper towels, which is prepared by hot set acrylic acid resin, polyvinyl alcohol, acidic or direct dye, and water. Preparation method for the dope includes steps: adding polyvinyl alcohol into water according proportion, stirring, heating above 80 DEG C to make paste, cooling below 60 DEG C, adding acid or direct dye to dissolve the paste, after completely cooled, adding to hot set acrylic acid resin and adding proper catalyst or cross linking agent according to need. The dope is coated on paper, after cross linking curing by catalyst, cross linking agent or heating, the product reaches demands of large tension, good oil resistance and water resistance, no decolorization and static resistance, and is a novel environmental protection product.
