Document Type and Number:
Japanese Patent JP2017066579
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rosin-based emulsion sizing agent good in storage stability and mechanical stability, and paper excellent in size effect by using the sizing agent.SOLUTION: This invention relates to a rosin-based emulsion sizing agent by emulsifying at least one kind of article to be emulsified selected from (B1) reinforced rosins which is an addition product of (b1) rosins containing communic acid of 0.1 to 8 wt.%, pimaric acids of 15 to 34.9 wt.% and abietic acids of 65 to 84.9 wt,% and (b2) α,β-unsaturated carboxylic acid and (B2) rosin esters which are a reaction product of the (b1) component and polyalcohols (b3) in a presence of a macromolecular dispersant (A); and paper obtained by using the sizing agent.SELECTED DRAWING: None
