摘要： A composition of matter for the neutral sizing of paper, paperboard, cardboard and other cellulose containing materials, is disclosed comprising water; a solvent which is unlimitedly miscible with water, particularly alcohol; a compound which undergoes a basic reaction; alkali aluminate; and a sizing component. When sizing is effected with this agent, the fiber containing suspension is mixed with a retention agent, before or after the addition of the sizing agent, with the sizing agent being activated by way of neutralization.
