PROBLEM TO BE SOLVED: To provide a lower cost and higher efficiency solution for decreasing density, increasing bulkiness, and maintaining excellent performance characteristics, in order to solve problems that, although low-density coated and/or non-coated paper products, cardboard and/or paper substrates are strongly required from the viewpoints of appearance and economy, print qualities and/or printability qualities are unsatisfactory by a conventional method, and that it is also difficult to achieve an acceptable smoothness target product using a conventional method.SOLUTION: There is provided a composition that contains an expandable minute sphere body and at least one ionic compound, and has a zeta potential of at least zero mV with an ionic strength of 10M-0.1 M at pH of about 9.0 or less, and methods for producing and using such composition. |
