    摘要: The present invention relates to a process for applying optical brightening agent (OBA) to a sheet of paper or paperboard substrate. The process comprises the step of spraying an aqueous composition comprising an optical brightening agent onto at least one surface of a sized paperboard substrate to form a treated paperboard substrate. The treated paperboard substrate includes a layer of OBA on at least one surface of the paper or paperboard substrate in which the brightness of the treated paper or paperboard substrate is greater than the sized paper or paperboard substrate before treating thereof.

    摘要: The present invention relates to a process for applying optical brightening agent (OBA) to a sheet of paper or paperboard substrate. The process comprises applying the composition comprising a cooked starch and a powdered optical brightener to at least one surface of a paper or paperboard substrate at the size press in a paper or paperboard manufacturing process to form a sized paper or paperboard substrate; and drying the sized paper or paperboard substrate to form a dried sized paper or paperboard substrate.
