Abstract: This paper first introduces the application of Alcoprint RTA, a polyacrylic acid synthetic thickener, in reactive printing. Then it analyzes the advantages of Alcoprint RTA. Finally, it discusses the property of polyacrylic acid synthetic thickener/sodium alginate composite paste. This printing paste retains the excellent functions of both sodium alginate paste and Alcoprint RTA.
